Remove Malefic Grasp and make Shadow Bolt / Drain Life our filler again.
Create a Glyph of Malefic Grasp turning our Drain life to have the same visual as malefic grasp.
Terrible idea. Drain life, maybe...But shadow bolt IS NOT going to ever be added back to affliction. It simply wont. It doesnt fit the specs theme and is slow and awkward. The spec is about DoTs and channels, not spammable bolts
 Return Haunt to the way it worked in cataclysm and remove the soul shard requirement. Instead, have soul burn modify it.
To be fair, i didnt play in cataclysm, so i dont know what it was like. I would like to see soul burn affect haunt somehow, though.
 REMOVE SOUL BURN: SOUL SWAP. Please, it's unbalanced and this is the reason for most of the MoP Drama in the first place.
SB:SS was never the problem. Trinkets procs doubling or more our spell power (or 100% crit) for extended periods with snapshots is the problem. That would exist even without SB:SS, but they are removing snapshotting in WoD anyway.
 Make Unstable Affliction Cleave whenever it ticks. It's unstable! So if it cleaved it would make sense.
Maybe if it was a glyph that reduced its single target damage if it was hitting more than one target.
 Give us back Soul Harvest. It was a spell every warlock had to love. It generated shards and healed us.
 Curses are cool, but they feel a bit clunky. Having to always apply Curse of The Elements in pve is annoying. Just make it a passive aura.
an aura, maybe not. A debuff from certain attacks (haunt, chaos bolt and soulfire maybe?) Either way, its 1 gcd every 5 minutes, not much of an issue.
 At lower levels shadow bolt has a 1 second cooldown, which turns into 2.3 seconds at 90. This causes caster form to feel very clunky.
do you mean cast time, not cooldown? If so, i agree. The cast time for shadow bolt does feel a bit too long. Incinerate for destro seems like a decent balance of cast time for damage, maybe SB should be more inline with that.
 Bring back the old Demonic Leap, and create a glyph for our current one.
No strong opinion here, I dont mind the current demonic leap but i dont know what the old one was. But, however, I would like to see it be a bit more like warrior heroic leap.
 Metamorphosis , In my opinion should become a stance like shadow form. The new 100 talent that causes touch of chaos to generate fury should be baseline. Make a minor glyph that turns the meta stance to the dark apoth wings. Dark apoth was false hope for warlock tanks anyways.
It doesnt need to be a stance like shadowform. Right now its a highly controlable damage cooldown and i like that. Turning it into an ever-lasting stance would not be a good way to go for the flavor of the spec.
Dark apotheosis was a mean trick. I for a long time held on to a hope for warlock tanking, and it was one thing i saw on the beta that made me want to play a warlock. Has its uses, though (tanking rdfs if tank is bad for example, and i used to use it in troves of the thunder king)
 Honestly, Destruction is amazing this expansion but alot of people still miss old aspects.
Agreed. I like destro right now. I would like to see RoF back to how it was in 5.3 though. Putting in extra effort/a bit tedious for extra dps seemed like a good trade and didnt make us OP. I would like to see some more spec-specific procs (Eg, a proc to let us shadowburn at any hp. If below 20% the proc makes shadowburn free)
Tier 15 - This in my opinion is a good tier.
Its decent. AoE harvest was better than the single target buff though.
Tier 30 - Demonic Breath should become baseline, and replaced. It doesn't compete
with the others.
Tier 45 - This also seems to be a good tier.
Tier 60 - Alot of people have problems with burning rush in PvP. Other than that, its pretty good also.
I dont think burning rush is much of a problem in pvp, seeing as it does drain hp. Also, blood horror seems pretty weak compared to the alternatives.
Tier 75 - Grimoire of supremacy was a good idea, but too many people missed their felhunter. Make this glyph increase our base pets damage and create a glyph for the new pets, or create an item that changes our current pets.
Grimoire of Service - It's not really an interesting choice. Most people choose it because they either like their old pet, or use it when their demonology for the extra spin.
Grimoire of sacrifice is good.
I rarely see people too upset about no felhaunter, although i agree a glyph for old models is nice. Service has uses on certain fights. If there is a major burn phase then an extra pet will be more valuable for that phase than a bit higher dps overall, or if you need two interrupts(felhunter) or an extra dispell(imp) at some point. A niche talent, for sure. But not needing too much of a change.
Sacrifice I like. I just wish they would stop nerfing it every patch (although i guess they need to, to keep it inline).
Tier 90 - It's good, but Kil'jaedans cunning should become baseline and replaced.
AD is nice and good how it is. KJC was nice back in 5.3, but its not too bad now- i prefer the 5.3 version though. MF was better in 5.3 also. double damage on rof doesnt mean much, especially on a min CD, because of how little it does anyway. I like a huge radius on my aoes but it wasnt game breaking because it didnt make them hit any harder.
