I stumbled onto this thread today, and I just wanted to let you (Life) know that I really enjoyed reading your thread.
I've been following the FE7 tier debates on GameFAQS for a long, long time, though I never posted. I never really fully agreed with the tier list though, and your play log kind of helped me realize that there are a LOT of misconceptions that people still have about S Ranking right now. For instance, a lot of the arguments on GameFAQS were about how the Snipers and Lyn sucked, but you used Snipers/Lyn quite successfully in your playthroughs. Also, the GameFAQS arguments put a lot of emphasis on supports... I can see from your play logs that supports might be kind of overrated - though I guess how useful supports are depends on play-style too.
Another thing I noticed is that you adapted the units you used or promoted according to how RNG-blessed/screwed they were. On GameFAQS, some of the debaters made it seem that one should *always* be using a "fixed-team" (Hector, Raven, Guy, Erk, Serra/Pris, etc.), and I can see from your play logs that this is not the case, considering that you used many characters that they would consider conventional... e.g. Wil, Rebecca, Louise, Rath, Nino, and so on.
Also, I enjoyed reading about the differences in the ranks between all the modes . When I get around to S-Ranking HHM, I'll be sure to keep a close eye on my exp rank, and when S-Ranking the normal modes I'll keep a closer eye on funds.
tl;dr version: I really enjoyed this thread and it really opened my eyes to the misconceptions I had about S-Ranking. Keep it up .
