ILU KUMA
Corselet, as far as I know, only offers ~16 extra TP per hit (with Store TP +40), yet in a 2-4 minute fight it adds about 5-10 DPS; as of yet I've only seen a DPS difference like that derived from weapons with more base dmg. In longer fights, when you aren't TP capped for the majority of the fight, that extra TP, as little as it seems, could go a very long way.
The way I see it, I could either get a little extra dmg. done per hit/WS (depending on meld), or I could have enough TP to use an extra combo or two. Obv, I'd prefer the latter.
