wow, i sense some luv in here. Tough luck, he gave his shorts to Chad.
Let's look at this matter in a diffrent angle:
If you're trying to invest your 20-use Elfire (which is pretty common in this game since they only have 20 uses. I'm assuming you know that), would you use it on a guy with shorts who would wear it down quickly because he can't inflict the same damage as Lilina with a single strike? I'd prefer someone who can inflict Lugh's x2 in a single strike. So, Lugh is more expensive if you baby him. And if you don't mind to use Fire with him, then that makes him even worse.
Sigh... it's not good to see that you turned this game in a MMORPG, where only base abilities and all that crap matters. It seems i thought wrong about Fire Emblem.
