Just maxed out my characters yesterday, and I was wondering why Noel only had about 600 strength without his weapons and accessories when most online guides seem to have Noel sitting at over 800 natural strength. Apparently I was supposed to level the characters up so that the COM, RAV and SAB bonuses land on 'large' nodes'. I never bothered with that, and leveled up the roles equally during storyline progression, and afterwards concentrated one role at a time post-game. While I haven't platinumed the game yet (still need Giants Fist, kill Yomi and get the rest of the paradox ending and casino fragments) I'm pretty confident that you don't need a max strength Noel to get the rest of the trophies, including Giant's Fist.
I'm not going to bother starting over as it doesn't seem necessary, but I'm just wondering how did other players progress their characters? Did you all level them 'properly' and end up with over 800 natural (no weapons or accessories) strength/magic for Noel and Serah, or did you randomly level them and end up with 'underpowered' characters?
