how much time you got? 
A lack of draw to new players. There’s so much history in this game that it’s frankly off-putting to people looking for a new game to try.
We need a reboot, not classic servers.
Not having Tuskarr as a playable race.
I started playing for the first time in a long time. The only real problem i have is how insanely i leveled up. And its pretty basic game play loop. Use ability, get free ability use free abiliy.
WoW will be fine as long as there is no strong competition for it’s gameplay. There hasn’t been in 20 years and i see nothing on the horizon.
However if a Marvel Rivals equivalent MMO comes out then watch out as WoW could get the OW2 treatment FAST. Probably not, totally different games but never say never.
Easy. The player-base. They’re the beginning and the end of the majority of the problems with this game.
Toxic community members setting an unrealistic high. I got kicked from a M+ group because I had to take time to dodge a move before I could poly.
They told me poly was an instant cast. It is not.
