1- I would go back to a talent tree format we had in the past. Being able to fully specialize in one tree or cherry pic a few useful but minor talents in other trees was fun and I felt like offered a lot more customization than the talent trees do now. Today it’s very lame for a game like WOW for as many years as it’s been out, to have such a lousy talent tree. Even worse is each tier for most classes is sometimes one or two abilities no one would ever use.
2- Reintroduce some abilities taken away during pruning. Not all, but some would be welcomed additions and abilities for each class and add some more fun back to them.
3- Five man dungeons that are challenging and fun to play, like they used to be back in the day. Mythics, speed runs, heroics, that can all stay. However would be nice to have some 5 mans or new mode added that makes them challenging past heroic levels, but not speed run or tank/AOE spank fest.
4- For me gear designs have been kind of meh. There are some ok pieces here and there but overall too much cookie cutter recoloring of said item for the fith or sixth time. What is unique again there are some ok pieces IMO but nothing amazing.
5- Take versatility off PVE gear, put it or resilience back on PVP gear and alllow PVP to have their own gear set. It’s stupid to get PVE drops with versatility on it, no one should have to put in time and effort grinds in PVE, to upgrade PVE gear just to get a drop and have it contain versatility on it.
6- Stop designing specs going ahead to be the same 123/ABC flow. In the past rotations were fun, for many classes that fun factor has been destroyed not allowing a more weave your ability approach, instead of monotonously repeating the same ability sequences we have now for hours on end.
