On the Skillchain issue:
Another reason to do it is that each consecutive Skillchain does more damage than the last. Assuming all Lv.1 Skillchains, and assuming every melee save for the PLD participates, that's 8 WS or 7 Skillchains. The damage will go like this: 50% -> 60% -> 70% -> 80% -> 90% -> 100% -> 110%. It adds up very fast. Of course, there'll be a couple of resists, but that's besides the point. And considering the jobs capable of putting up the biggest WS numbers are going last, that's all the more reason to try.

Edit: If you manage to make the 7th Skillchain a Lv.2, it'll do 175% damage.
