As much as smart skill management means not blowing your load early, being overly conservative is also bad. You shouldn't be hp+ spamming Bahamut and finishing with 4+ skill uses left. Have had several fights where I'd be tapped on abilities (WoL, Cinque, Paine) and the other members able to go another half dozen+ rounds.

If you're playing a more support oriented character (WoL...), don't lead the summoning charge on Bahamut. Let the big damage dealer(s) start the summoning party. Bahamut isn't going to start Cure spamming out the gate and allowing the damage dealers to summon first lets them (if they're playing right) use abilities (cp65...) to get set up for dealing said damage without wasting summoning turns. Had a fight last night (as Paine) and one just now (as Cinque) where good ol' WoL immediately summoned in the last round and both my turns were gimped as I hadn't been able to get anything going yet.

It's the little things...
