Don't get me wrong, I appreciate open world content and instanced mass-player content, like Dragon's End, Dragon Storm, Dragonfall, Auric Basin, Tangled Depths, etc
But Convergences feel like an absolute slog, the mobs are all bullet sponges, the champions (and there's a lot of them) don't particularly feel rewarded to kill, and there's no special mechanic, it's just "Kill this 5 champions, then kill this last champion, on 4 different places of the same map, that look exactly the same" and at the end we get a legendary mob that has some mechanics, which is okay
And this seems to be the "core" piece of this expansion other than spamming rifts, if you're looking for the leggy open world armor, it's a shame that it's lacking more love put into it...
