Earlier today, I was thinking to myself, what would make me and my wife and friends come back to WoW and had what I think is a pretty decent idea.
What WoW really needs to do, if it wants to draw in numbers again, is release a different type of expansion, all focused on the "other stuff" to do in the game that isn't raiding. No new level cap, no new continents. Totally scrap the time they would use making these normally, and do the following instead:
-Player housing
-Guild housing
-Ways to decorate your house (items from raids, to 5 mans, to quests, etc, and ways to show this off as a badge)
-Find a way to make all the old raids relevant again (whether scaling up or down).
-Tons and tons of transmog gear scattered throughout old content
-Tons of new pets to collect
-Rare unique items off of new super rare spawns scattered throughout the world, everything from vanity to special clicky items, etc (Think Jboots, mounts, rare pets, etc)
-A new raid tier for the hardcores and lfr users
-A good chunk of new 5 mans
-Actual battleground ratings for individuals when queuing normally
-Maybe make an actual good battleground matchmaking system based off said ranking
-Actual good unique PVP rewards that dont just require honor/conquest points
-A trading card game or something along those lines (integrate hearthstone?)
-A WPvP area like Wintersgrasp
-Multiple super long legendary quest lines different for each class (with weapon rewards etc, with unique effects like EQ that make them stay relevant, stuff like the fire cat druid staff)
-Make these mostly solable or small group content like the old hunter epic bow/staff quest, that are hard as hell but rely on skill and are solable only, and don't tell anyone where they start, or make the starting item randomly drop somewhere in the world so there isn't a farming for first item roadblock of 1000's of players.
-Can even make the quest chain go even further to make the item better (2 ilvl upgrades or whatnot), through hardcore raids etc to appease the hardcore.
-A bunch of new/revamped holiday events
-New world events with cool enough rewards to draw people out of cities more (think fishing event x10 with unique rewards)
-Multiple new armor model sets for each class
-Revamp tradeskills, and maybe do something cool with fishing
-PVP raid bosses, like raiding Org or Stormwind and killing bosses would give actual uber (legendary?) rewards.
-Maybe a new class unlockable by some long epic quest chain
-Some sort of bounty system, where you can put bountys on players? And maybe where NPC's can put bounties on rare spawns, for unique item rewards? All sorts of things you could do here.
-And last but not least, AA's! Well, something just like it. Grind xp/old quests for small perks, new talents, etc.
Just tons of other non raiding/non dailies stuff to do, the sky is the limit. This will give them a good base to expand on too down the road (adding new housing items, etc). This is honestly what I bet most WoW players would want, and what would get them to resub. Honestly all thats going to be left soon in WoW are the hardcores. Casuals eat shit up like the farm lands, pet battles, quest chains, fountain coin fishing, etc. They need the casuals back, and a new +gooder raid expansion with some new levels and raids isn't going to cut it anymore. And we all know as long as there is a raid on the horizon, poopsockers will never quit for good. Make WoW an actual "world" to live in again, rather than the same old action raiding game it has been for years.
