1- Unnerf Cold Heart > it’s pvp modifier is coming from old days which isn’t justified anymore. This talent does 500 DPS in a game where people have 1.000.000 health.
2- Buff Cold-Blooded Rage > waste of talent points in current version
3- Bonegrinder build up phase buff is too short, it falls of very easily. Make it 20 sec instead.
4- Make Bloodforged Armor %25 physical damage reduction.
5- Make Remorseless Winter replace Death and Decay and make every talent that buffs DnD buff Remorseless Winter instead. (this change alone would make spec much better)
6- Buff Soul Reaper damage by %50 (pvp only) > this ability is supposed to be an skill oriented execute but main damage abilities (frost strike / obliterate) hit harder than it.
7- Frost strikes should reduce enemies healing taken by %15-20
These changes would be good for starter.
