I know I'll probably get some disagreements here, but I feel like ANet would probably do well with more mounts. I personally love my broomstick, and I feel like they could probably make mounts fairly useful in future areas. That's a separate discussion, but I definitely agree with you. I want to make my character look as unique as possible, and dyes aren't going to be enough to do that. I can only stare at purple and green dragonfly wings for so long before I get sorta bored.
This is just a solution to a problem, that doesnt exist. Wasting time to make things specific for mounts instead of just working on actual content is silly. We have a waypoint system, accept it and move on already.
Personally hoping they do expansions they way they have done in the past, add a ton of new content, a story that ties in and in some cases ties into an even bigger story we dont know about yet, new classes, weapons, skins, all that wonderful stuff while keeping it fresh. My opinion, were going to Crystal Desert/Elona next.
