You aren’t supposed to use Brann as a tank, not yet at least, so everyone who had issues because Brann got feared and Zekvir followed after him were messing that up. Ain’t a problem with the fight.
The room was designed for this encounter because it was generic. There’s no line of sight requirements, there’s no pools on the ground that requires more space, there’s nothing but you and the boss. A generic room is fine when you step into what’s essentially a boxing ring.
Safe to say, they fixed the issues. You not being able to do it because of “tuning” or “testing” issues is quite literally a skill issue.
No, you aren’t getting mage tower rewards from this and no - your critiques of the fight has been irrelevant since at least September of last year.
This is the reason you and others have had issues with Zekvir; the entire point of the fight is that it was a rhythm game. If you stayed calm and did the mechanics, and you get the kill. It may take longer and sometimes you get unfortunate overlaps.
That happens. All that happens is that you try to deal with it and if you can’t, you go again. Not every pull is going to have a bad overlap, so staying calm and just doing the mechanics is how you were supposed to do the fight.
Ain’t more complicated than that.
