Just wanted to add into this thread one of my experiences.
I've been doing the company leves at Halatali alot in order to rank up in the immortal flames. There is a leve there that appears quite often where you have to kill as many enemies as possible in 15 minutes. It gives you a minimum quota of 6 mobs, but you can keep going after that and get extra kills for bonus seals.
As a thaumaturge I have a hard time killing enough monsters to get the bonus seals because I have to stop and wait for MP after only a few kills. As an archer however, I can usually easily kill 15-20 mobs over the quota because I don't have to wait at all. 1k tp is enough to execute a string of WS that would normally take 3-5k TP to execute.
Compared to melee, a mages resources are extremely finite. I feel mage combos should have the mp cost completely waived in their combos as well in order to make it balanced with melee. The DPS won't be too overpowered because the mage will be forced to stop DPS because of enmity.
Please don't make mages fight for resources when melee has an infinite supply of it.
