- Housing
- Scale every single dungeon/raid ever put into the game to max level, including their gear. Separate them by difficulty tiers and slap a LFR on it (not lfr difficulty, just a way to find groups for the dozens of raids). I don't care how much of a nightmare it is to balance, this is about FUN and it would be FUN and provide near limitless options to min/max with rather than just 1-2 generic builds per tier. We'd have infinite options.
- necromancer class. How we didn't get it during the DEATH expac of SL is beyond me
- bring back meta lock, while keeping DH untouched.
- professions. remember when they were good? As ippollite suggested, make the old dungeons/raids drop HOUSING stuff for housing. Maybe skinners/LW can make head trophies out of the final bosses, or BS/Tailors can "mimic" the outfits of NPC's in dungeons to copy/paste their outfits into a collection, etc.
- NO MORE SEASONAL SYSTEMS.
- Talent trees, bring them back for real and not this D3 rip off we have now.
- Speaking of talent tree's, while you're adding them back in, add in the missing talent abilities we SHOULD have got the last few years. We should have 2-3 more abilities than we do right now at the minimum.
- Fire the writing team, or at least put someone talented in charge of oversight because the story right now is the equivalent of a 10 year old playing with dolls in the bathtub. It's pathetic, and that's being KIND about it. It is, by a large margin, the worst story in any major MMORPG. FF14, ESO, even SWTOR do story telling better. WoW has amazing setting and characters, and has incompetent writers who have NO IDEA what to do with them.
- Speaking of better writing.... add villainous options for BOTH factions. For the horde, especially. I didn't roll zombie evil wizard (undead lock) to be the hero of azeroth, or champion of light. I would rather be Sylvanas or Garrosh than Thrall, and i'm NOT alone. There's quite a few of us old WC2 horde survivors out there who want a darker side of azeroth.
