[1.2.300] New Class?

There's one alternative to making higher level training areas. Make it hard to gain access to just like Temple of Time, but harder of course, but also implement a level limit on portals an mini-dungeons, and make it so the training map is impossible to AFK in. The trade off? The higher level mobs have insanely good HP:EXP ratios, like 10:1 EXP, or as low as 5:1. So a 150k mob will give 15k-30k EXP.

Difference between being hard to access and being time consuming to access though. Time temple was time consuming. If they wanted to make O4 hard to access, they should have had us kill 999 mobs and then kill each boss (the bosses being tougher than they are now) while the boss itself having an insane time limit (5 minutes for dodo, 7 for lily, 10 for lyka). If you can't kill the boss in the time limit, you have to hunt 999 mobs again.
