The KV-1's performance has been on most peoples' radar for much longer, ever since players started using it more and more during the past year. It has been pretty dominant in 2v2 games and automatch 1v1. But borderline overperforming doctrinal units were not part of the scope of the recent balance patch, which only focussed on the core armies and highly problematic meta doctrinal units/abilities. Next patch will be commander focussed, and the KV-1 will definitely need to be looked at because it's clear it needs a small adjustment to be a bit less cost effective.
Spec flares have been OP since forever and your last comment about it was "yeah but that what keep the commander useful so we don't nerf it". What would you do to keep KV1 commander relevant if you nerf those?
