hmm.. many condition. in KR its very rare to get critical in pvp. cause, defend from players and mobs. and if the opponent use armor with 31% reduce crit or use 21% reduce crit chip. that why in pvp, i use +X all properties, and 1 set cc MA ring or use 2 ring 7% cd (optional). cause, if i'm not get critical in dmg, but i'm still get 10-13K no crit.
