Honestly, TP as a monster mechanic is really stupid. It wasn't well thought through at all.
If there wasn't TP for monsters and RDM was given a trait like "AoE damage not targeted on you does a lot less damage" then people wouldn't care if RDM melee. As long as they could keep up all of the other stuff they do, no one would care.
Sorry for a real post in a silly thread :/
There would still be a problem <_< they'd be subject to mobs AoEs which would deplete their MP faster dealing with themselves because they wanted to be stupid, AND, constant switching of staves would destroy any minor TP they gained since the last...
I'm pretty much career RDM, I was RDM on my first char, then after I quit and came back I was RDM on this char, both 70+ I knew my place and accepted it.. If you want to melee so bad, then level a job where your meleeing would actually be beneficial.
That's IMO anyways.
