1) Ascended Characters with a golden name. The text of the name of characters who beat their mirror self should have gold writing of their name, so people don't accidentally go into a bad team due to other parties choices. This is also advised when parties around Guild Wars want to try the Uber-Exploration quests and want to instantly want to go through with other Ascended characters. I'm not saying change it completely, just show who have ascended and who have not.
2) Access to Amnoon Arena. Forgive me for saying this, but how the hell are people supposed to access the desert arena if the gate isn't open at all? I'd suggest that the gate is open at all times for people to enter the arena, even if they have ascended.
3) Higher Morale Bonus (Morale Boost). This is one of the areas which should change a lot. If people get a 60% DP then why not increase the morale of some areas and missions to 20%? This will reward players who have spent time succeeding in the missions or bosses and want to get even more statural bonuses out of it.
and lastly
4) Improved Guild Interface. There are good things like an announcement on the news screen, But I'd really want people to choose whether they want to see who isn't online or not, and if online, to click on that name and see what level their character is for making choosing parties much easier than asking all the time for help on "this quest" or "that mission". Lastly there should be a tab on from the Guilds showing ArenaNet/NCSoft's announcements without regularly checking the website from time to time to see what has been added or not.
