You need to say at this time, you needed it for mp so you can't compare it with BLM we got now. And ppl asked for multiple skills like extra magic def down, mp regain etc. If you implement one skill like that it won't break balance or just abit but all of them, and WSs when you dont even have todo anything to get your tp.

Game changed alot and will change alot but giving mages additional WS spam and some powerfull ability would make them uber and that willl not happen. Give them a melee tp move that needs accuracy and its fine. Then they have a possibility to use their TP.
