full power reaper - ninja in pvp

when i was full crit i noticed i get few crits in pvp so i reduced my reaper crit and got more power
my dmg became so bad in pve , and i think it's better in pvp
is going full power/atk spd is better in pvp for all classes ?
thanks

up

@Mitojen thanks for your answer

Quote from DDamos

Play full power reaper requires skill and experience. it's not easy to play without atk speed

i will take atk spd , i mean power instead of the crit factor
how is that in pvp and pve
thanks man
