This addon manager takes out a lot of the “manual work” with keeping your addons updated and is a great way to install many of the other addons!
As Guild Wars 2 began shifting from DX9 to DX11 many old addons were broken. Currently the addon manager is my first recommendation for getting your addons set up and working properly. An up-to-date download link is in the description.

You can install ARC with the above addon manager, or as a standalone program using the steps in this video. This video ALSO includes a guide on how to test your dps to try and improve yourself in the practice room.

You can install Radial with the above addon manager, or as a standalone program using the steps in this video. Radial allows you to bind all of your mounts to this “wheel” which requires one key to open, so you can feel like you have 8 mounts accessible from 1 key binding instead of 8 seperate key bindings.

Got any extra accounts in your household or alt accounts of your own? You can put them to work! Log into them once each day for daily login rewards and periodically mail the money to your main account. This program allows you to do this easily without having to type in the usernames and passwords of your various accounts every day.

Blish HUD is the penultimate addon of addons. A comprehensive collection of addons to take your gameplay in Guild Wars 2 to a whole new level of customization. Elements like Radial Mount Menu, Event Tables, Raid clear information, and so much more all rolled into one! This is a one stop shop and the guide to show you everything you need to know!
