Yeah I normally don't like when they go nerfing high tier feats. Sometimes they wind up nerfing them so bad (like protected revive) that they become worse than tier 1 feats. Or in Protected Revive's case worse than the perk Rising Dawn. But I think in Warmonger's case they really got to go through and nerf her unique feats. Her tier 1 is as good as Nuxia's tier 4 infection with half the cooldown. Her tier 4 instantly wins ganks or kills the commander in breach. It doesn't help that she benefits either from all other Warmongers on her team using corruption feats or Nuxia using Infection.
My big concern is that they don't nerf Nuxia's infection too, once they do nerf Warmonger's feats, because I don't think most people feel Infection is really an issue right now.
