Sorry for flying mount click bait title, but we sooner or later need to start looking at how gliding mounts should work. Because:
1. They are 10x more fun and interesting than flying mounts
2. Only a few will have true flying mounts, and they suck so who cares about them.
3. They can potentially be designed in a way that rewards skill, planning and knowledge about the map.
Guild wars 2 has by far the best gliding mount feature of all time (for an MMO). So lets start there. We should learn from it.
Ill link a video showcasing how gliding mounts work in GW2.
