When damage variance from dh/crit/crit+dh looks bad? When you have a bunch of skills with 2000+ potiencies on 2 min cooldown so if nothing procs it will look bad: missing damage from gambling you can't even control.
But is it because crit mechanic overall is bad?
Or it comes from devs lazyness to even play a job to certain level so they put such drastic potencies in 2 minute cooldowns so it's either win or lose every 2 minutes.
Auto crits is terrible approach to try to fix what devs had did themselfs. Is it hard to play with potencies of every skills in rotation to just simply spread some bits from 2 min cooldowns into rotation loop? Oh wait, this requires some competent person to do this work.
The genius behind SAM auto crit thought that some damage variance will be bad in ultimate ... Thanks to him as SAM i can't find any static to do DSR... You either play NIN/MNK/DRG or switch roles. SE literally ruined first ultimate patch for me.
And to add insult to injury as recent Live Letter states they are going to do adjust crit buffs to work with auto crit abilities ..... which 99% is going to be just plain damage buff. This will easily lead to homogenizing buffs even more - all of them will be same % damage up after some patches.
After WAR, SAM who is next? DRG (which obviously on the way), DRK (this is literally 5th dps at this point with these 2 minute potencies, devs destroyed SAM/DNC combo and now sometimes DNC should switch DP to TANK in DSR ...), GNB, NIN (that is new SAM of this god awful patch)
