Why you serious about ppl getting all 50 in 2.0? Because no matter they using your mentioned exploit or not, they will be all 50 in no time.

DoH : rest exp + eng manual + HQ craft can get you to 50 in few weeks.
DoL : grind leve + survival manual + rest exp can get you to 50 in few weeks.
DoW/M : most of ppl love pl, and if some high level willing to PL, it's no problem. The goal of playing game is to get max level isn't it?

Item and market price : you blame only bot for cutting the price...I think everyone can cut the price not only for botters. And I still find myself able to make some profit out of market everyday, just buy mats, craft and sell it. Btw, if the item price is low I think most of ppl will be glad.

OP topic is full of selfish mind and just bias with other ppl that better than him.

If you hate this game enough, play TERA
