Heroes right now is a massive improvement on Heroes back then. There's a lot more to do now (even if I think a lot of the game's modes are filler), you almost always have something to do every day. Also, the way they now add a 3*/4* unit directly to the pool (assuming they're bringing this back as of the current focus) and have a separate unit as a 4* focus is honestly what I was wanting them to do since the first year, so I will say that I've been heavily pleased in that regard. They even have 4* focus on seasonals now which is crazy! I have some issues with AR (AR Fortress is pointlessly punishing for new players), but with Peony/Eir and Altina (who should've been permanently free tbh), you can easily make your way up to t21 as a f2p player, and I feel like that's worth praise. Sparking is also another great improvement, though I feel it should be expanded to legendary focuses. More on that later. Accessories and Aether Resort are really nice additions, the former especially so. You get more value out of your units when you can give them a beard or a helmet. Overall I enjoy Heroes as it is now, but there are a lot of things I'd like them to work on.
Heroic Grail distribution is horrific for example, either that needs to be fixed or they need to make the grail cost cheaper. If you missed a TT unit it costs almost a year's worth (my math is probably off by a month or two) of grails to +10 them. If you're a new player that means you don't get to use grails on any of the other units you missed if you have a grail project. I see no reason why characters with little to no gameplay value such as Tobin, Clive or Canas need to be this ridiculously expensive. A more baffling thing is that whales can't even just literally whale for them to get the necessary grails. What's the point? If they're worried about Aversas/Kronyas, almost everyone that would +10 them has them already. Please, just give more grails. Please.
Many choices with 5* exclusive units are dumb. Is there anyone really whaling for Lugh or Ranulf at this point in time? It feels like things like this are only there to be an inconvenience for people that like them. They don't want to harm their "bottom line" or whatever, I guess, but I don't think they're really getting that much profit from it. They should've kept doing demotes for 5* units. Also, generic weapons shouldn't be 5* exclusive. All the Serpent tomes are, which is awful. It just restricts SI possibilities even more. I guarantee all Fox tomes will meet this same fate. I'm pretty sure Safeguard+ and Barrier Lance+ are 5* exclusive too, and who are they on? A generic sword dancer and a generic blue flier. Many units like this should be demoted for the greater good. Also, while we're talking about the normal summoning pool, colourless is still hell. I don't really know what my ideal fix for this would be, but some characters may just have to be removed from the pool entirely. Pretty much every gen 1 healer has worthless fodder due to how poorly handled they were at the beginning of the game. The best you can hope for is Miracle, the only other potentially valuable stuff would be their generic staves/healing skills that you might need specifically if you're building another healer, and then that costs 20k feathers. I think it would be cool if FEH introduced a friend point system like some other gacha games. Using friend points, you could roll on an FP focus that has only old 3*s/4*s to clear up their respective pools and keep them easily available, but I've been sending them feedback for this every now and then since launch so I really don't expect it to ever happen.
The way refines are handled is also really annoying and tedious. 4 per month is beyond ridiculous. And with them using a gen 2 unit to take a slot in each new batch we might actually be waiting until next year to have all gen 1 units get their refines. Unless they just do a massive batch of refines for healers at once, since they've decided to ignore them for years. I can't believe we've gone through two gen 2 5* exclusive green dragons without giving Fae a prf. I honestly can't imagine how long it'll take to get to current gen units' refines. The fix to this is obvious...just release refines more frequently.
I don't like legendary focuses. At all. There are a lot of skills locked to these characters, and if one of them is a favourite you're in for a rough ride just getting one of them, let alone daring to +10 them. I don't remember the exact numbers but I think it took inbetween 2 to 3 times the amount of orbs to +10 a legendary unit compared to a normal 5* focus unit. To be honest, I don't know the best fix for this, but I think adding sparking is a start. I know IS don't want to make their premium scoring units easily available, though, so I doubt anything will change with this unlike some of my other issues, but there's nothing that makes me want to not roll on a legendary focus like knowing that I could use 300 orbs just to get only characters I didn't want/can't even make use of. Some early legendary units are so bad. I sure as hell would never spend money on these things either.
Personally, I don't think powercreep affects all that much. My Sophia still takes care of weirdos like normal Mareeta and Fallen FCorrin, but I will say that characters like these are pretty dumb just by concept. I don't see any reason why Close Call or Repel, or the former two's prfs needed to exist. These characters could've been made good without them, but I guess someone on the team really just wanted more one man army characters. When other characters require some decent positioning just to maintain their buffs, these guys can come in and get them for simply existing, it's kind of sad. This isn't really necessary, but I think they could give older units more buffs. I forgot where I read this, but someone suggested old units got a stat boost for being +10'd, that way it would take some dedication to make that unit better. I know dragonflowers already exist, but those would get expensive really fast.
While not as big of an issue as the others, the distribution of sacred coins could be better. For old players this isn't an issue, but I don't know how long it'd take for a newer player to catch up, probably years...
If any one of these complaints are addressed this year (hopefully one of the first two), I will consider that a victory.
