What level range training spots is more in demand?

Mages sure as hell do count. They need more variety for 140+ period, around there Newties and Skeles start getting really lame. They are still good, no doubt, but when you have to compete with everyone from lvl 100-200, it's bs. Oh wait, no it's, from level 80-200, cause people like to train places where they don't belong, taking one spawn, and not allowing anyone else to train there, without calling in an army of people that should be training there with you. Then again, Nexon can just release the mini dungeon for Newties, and that'll make things a lot better, but they'd still need something for 160+.

And when did they ever say zombies were enough? People were complaining about that being the last training spot from just months after Orbis's release, up till they had Ludibrium.
