1. Make classes easier to play, i bought this game for my kid, he couldn't understand the rotations, i couldn't either. Takes eons to kill mobs and he went back to playing wow.
2. Dailies, go to ascalon, gather lumber. Great but where is ascalon? Why is there no point marker? Nightmare for newer players who don't know the map
3. Crafting is too convoluted. windows upon windows. Make crafting simpler and mats easier to get. Eg if a legendary needs 40 woods 50 ores etc and 15 prerequisites, if i have ALL the mats give me the option to craft it immediately. Fewer clicks ftw
4.Give us an option to hide friendly effects. Its a mess with all the cosmetics, i like to see cosmetics but not when i m trying to kill a world boss and have all these flashes in my face
5. Maps are great, i like HoT and PoF biomes, but i die soooooooo easily it makes me want to stay in Tyria. Those maps are empty, you ever wonder why? Only very good players play there, Sure i m a bad player but when i fight x mob and y-z-w mobs join the fray and start attacking me what gives?
If you want to stay relevant do these and many other great suggestions in this thread. If not, oh well i can move on
