While mounts are fun, they do introduce all sorts of design issues for towns and the like. I remember in early days AoC people would park their mammoths across the street leading to huge traffic jams of people trying to get by. Not to mention the infamous Benny Hill Horse clip from AoC. In Wow, mounts just make the towns look like huge parking lots and you lose the atmosphere of the place amoungst all the glowy stuff
Certain streets and paths would need to be changed so that clipping didnt happen, or people didnt look silly trying to get by. Not to mention the jumping puzzle and terrain issues you'd get by allowing them
I agree with this completely. But they did add a ride-able broom in the Halloween update and they said they will likely add more (?). It can be seen as a mount. Just add a speed buff on this while riding and there, you have your mount.
Like I said, I don't want to see proper mount like horses, mammoth, unicorns or whatever, but the brooms could make a useful travel item. The only downside is we're forced to be in town clothes and we can't use it when we're attacked, but otherwise, it's still a fun thing to ride.
