Ditch TP in exchange for unique systems.

[Elexia]

They still all worked different and SCH used stratagems to enhance its combat not tp based or mp based, DNC used tp but it was the first class to use tp for other things besides ws, and they also had some kind of point system as well but i forgot what it was called, and bluemage was just different cause equipping spells gave different traits etc to make you different from the next bluemage, Pup was was different, the master was the same as a gimp monk but the auto made the whole class play different from the other's. It's lots of things they can do with the system but no matter what system they add its just a mask for how often you can use an skill.

Trust me, most people can understand that they play uniquely even though it was tied by the "same systems", but you forget you mentioned FFXI and therefore your point is nullified according to these forums.

Speaking of nullifying points:

See? SE is more than capable of working something out if they so chose.
