I just simply think that in a vast majority of the cases, a crit will benefit me and the raid group more than a dodge.
A crit is always useful, a dodge is very rarely useful.
For the current state of dodge/parry to work good.
The damage in-take per attack round needs to be very low compared to your HP, so that healers can have you wobbling around 70%~ life with mana effective heals.
Or you need to be attacked by a big number of attacks each round making it less RNG if you will get a dodge/parry that round or not.
The first is just simply false in every scenario in mop except perhaps LFR and 5HCs. The second is false on every fight except Wind-Lord maybe, it is borderline the number of adds required imo. Not enough adds on empress. Possibly Elegon adds but wouldn't even consider that.
Feel like the second combat table for avoidance really screwed them over, lost so much of the value right there.
Not to mention the insane DR atm.
