Zekvir's Lair is impossible to complete by "normal" means

It was ‘doable’ before by some with Buff Brann.

But now? Yeah ‘fixed’ Brann is no longer the help needed to overcome.

Proper tuning post-nerf-Brann (his minor ‘buff’ after being nerfed to the ground is not the solution) now it needs tuning to accomodate that change.
