They are loating away from current stat design where some classes benefit just from 1 or 2 stats to more "monkish" style where every stat feel more or less right.
Still i see no real reason to be happy about 200% crit mod everywhere just not in PvP.
Also, I am not quite sure about crit heals in PvP, 10%-100% heal crits are just as bad as 100-0% damage. 150% mod across the board would smooth it all at once without the need of all these "altering reality" band-aids like power/resi battle fatigue and now different crit modifier in PvP and PvE.
There is no benefit for this, at all.
The only downise i can think of, dragonslayers would have slighty smaller crits too w@nk about, but they are going to have all damage reduced by like 80%(?) so anyway...
