To start things off, everyone and their mothers acknowledge that affliction locks are hurting right now and something needs to change. I've decided to lay out a few viable options to put them back on track.
1.) Increase DoT damage by a flat 30%.
- To compensate, Malefic Grasp damage would be reduced by 30% (to prevent PvE overkill)
- Damage from dispelling UA would be reduced by 40% (to prevent instant gibs on top of hard hitting dots).
2.) Make Malefic Grasp Uninterruptable
- Allows the warlock to have weak hitting dots, hard hitting dispels, and a hard hitting channeled spell.
3.) Make Malefic Grasp Do All Its Damage Following a Full Channel
-Allows for some nice burst set up...after you finish channeling it, all the damage it would normally do over the casted time would be dealt upon completion.
4.) Combine Malefic Grasp and Drain Health into One Spell
-Increase to survivability
5.) Revert Haunt to Cata Conditions
- 8 second cooldown, does not require soulshards, returns health to the caster following its duration completion. Soulshards are now exclusive to soulburn. Allows DoTs to hit harder, but requires some set up.
Just some thoughts to throw around...personally, I think combining a mixture of suggestion #1 and #5 would be optimal.
