I feel it was slightly rushed but then again, what can you do when you got people rushing you?This server isn't ready. Not enough caves, weird drops, no good pets for taos (a lvl 65 pet hits 70)...
There are limited caves, but your not meant to level fast so i suppose your meant to stick at them caves for a while.
Until he adds more
Again this is a x16. Tao pets are not meant to be uber, maybe try group hunt on support class?
