I like the riding skill change a lot. Mainly because I never remember to buy the riding skill when I reach the level and just keep running around :D I also keep forgetting to put my skill points to use too...
I started playing when Shadowlands just came up, so I have almost none of the allied races unlocked. I've been looking forward to doing that, but just haven't found the time to do that. I suppose all the quests etc. will stay in the game, but now there's less incentive to do them.
I'm still waiting for the cross-faction play in open world and queued instances too, but maybe that's coming in the future too.
