My review:
in General:
the server seem to be full of arabs, arabic is main language. Anyway, players always complain in chat saying management are not good enough, people leave the server because there is nothing to do.
Difficulty

Hard)
Easy to level up character , manually level up pets, no equip npc, no skill cards npc,(failed +3 with ancient skill cube), expensive items over-all and, taming is ****(14+3 taming & 0/30 kentarous), staging is half good, if you have money then it's cheap to buy what you need.
If +1 skill cards are sold then it would be better. enchanting isn't that great and taming need to be high at least for tier 1 - tier 4.
PVP:
would give 7/10.
PVE:
at first it's fun, 6/10.
Over-all: spending 3 hours failing kentas and spending all your starting money to make a ****** belt pets isn't fun in a private server.
