We are always working to bring more content to Aeternum; if you’re tired of the ECRs/WTs, you can do 3v3 Arenas, finish the MSQ or side quests, see how far you can sneak on your own through each Elite without dying, join an expedition run via Group Finder, get starred at Expert on all your music sheets, flag outside a settlement to draw out some enemies, capture a fort for faction control points and to advance your PVP reward track, or make friends.
I’m sure others in the forums have suggestions to for what to do when you’re tired of ECRs. I personally do side quests that I haven’t completed yet, sometimes go back to the repeatable ones, or I get a group together to run mutations. But it’s up to you.
There’s a lot to do in Aeternum, more to come.
