Nice one. Why don't you post this to the official forums as well?The changes so far are misguided and will cause more problems than they fix.
Dev Problem = locks are too durable in raids
PVP Problem = locks are too squishy in pvp
Actual issue = soul leech stacking to 100% of lock's HP. Cap SL's shield to 30-50% of the lock's HP and leave 10% static dmg reduction in.
Dev Problem = all ranged cast too much on the move
Better Solution = allow filler spells to be cast mobile, KJC on use lets all spells. Similar to shaman/hunters. IE we could cast MG/DS, shadowbolt, and incinerate on the move with KJC but nothing else without the on use. Good middle ground.
Dev Problem = locks have amazing aoe thanks to MF
Better Solution = make it a passive but compromise on the size from 500% to 250-300%. We don't need another CD...we are getting into button overload again.
Side effect = 90% of locks will be forced into AV.
Issue = the on use is almost never a good idea to use since it makes the passive go away. It also is too weak in pvp but making it strong enough in pvp would make standing in stupid a strat in pve.
Solution = Keep the passive active at all times. Let the on use increase the reflect. Give it separate values pvp and pve. Something like 50% on use pvp, and 10% passive pvp. Compared to the monk version its way too weak. A single hot, shield, etc negates it entirely. As it stands you can get beaten to death and the attacker would be at 95% hp. Anyone NOT make that trade in pvp? Even the on use would make the attacker be at 80%. It should make them a viable swap target at least which is around 50% which is exactly in line with my suggestion.
Issue affliction pvp: non dr interrupts, stun dr, silence dr, misc other cc's = a 0 casting environment. Since our dots don't do much damage but act more like debuffs to fuel MG damage we need to be able to use MG in pvp. Trying to make dots do all the work is super tough to balance vs pve.
Solution: make MG, DL, and DS be uninterruptable like hunter steady/cobra.
Soulution pt2: to help dots be meaningful without messing with pve and without making darksoul+trinket too powerful (since the delta between baseline and that is huge) tie a 30%'ish buff to dots vs players to a new darksoul glyph.
New darksoul glyph = your darksoul now grants 15% stat gain but has a 60 second cooldown. In addition periodic effects tick 30% harder vs players.
Destro PVP issue = no way to use chaosbolt vs a team of similar MMR, especially not the "all cd's one every 2 min". Without that spell destroy is too binary on its use and has little to no pressure without it.
Solution: Since CB was nerfed vs players 25% let it be instant at 3x backdraft. Not out of line whatsoever compared to pyroblast streaks vs frozen, frostmage instants/procs, or even ele burst via instant procs, and certainly not out of line vs hunter "instants".
Demo PVP issue = DF generation way to slow, losing fury shifting in/out of DA when other classes can use their defensive stances with far less penalty, RNG swings on CW making it hard to balance.
Solutions: DA to meta shift without complete DF loss. Gain DF when doom is dispelled AND procs an imp. Double normal/pve DF generation vs player targets. (esp if we are not doing anything w' DA) Finally treat CW like CB/soulfire...cut dmg in half, it always crits, scales with crit, revert the old dmg nerf.
Dev Attitude: we wish DA didn't exist so that's out, we don't want to try to balance demo in pvp so we would rather have you play aff.
The base issue is that balance aside the 5.4 patch is making warlocks far less fun to play mechanics wise. It making pvp utterly painful in a time when pvp participation is dropping. There seems to be a disconnect in terms of how devs go about "fixing" things suggesting they don't main a lock and tend to not listen to the community when it comes to things that pertain to what makes the class fun to spend time on.
