Dispel Magic (mage spell) not showing up in the list of debuff spells, this seems to be a issue with the original version wich the devs fixed in later version which offcouse dont work on 3.3.5. (Going to look in to this).
@Aelvi You should get the ascension-specific version from the addons discord: https://discord.gg/xM4cf8XS4s
If there are no ascension-specific version of the addons you need, either in that discord or in the launcher, you should always use 3.3.5a versions of generic addons, since that's the client version ascension runs. 3.3.0 could also work if there is no newer available.
I had the same problem with the Draenei starting zone but I have not experienced it on Prestige playthrough so hopefully you can get through it the first time around by using the zoom in and out trick.
