It reminds me so much of Aion.
The grind isnt that bad, atm, im level 38, max is 45, so not bad, but ive read end game grind is the real terror.
Some things have been done so well tho, cross server dungeon searching, cross server PVP arenas, arenas arent gear dependant either, everyone has the same gear, seems a really good game currently, but it all depends what the end game is like, its still very popular in Korea and has been out years there.
Defo should check it bro, come my server, Starfall Crater or something.
