Recently heavies got their Punch Through ability nerfed , like it barely does any damage now and it can't kill now, maybe because a lot people complained about it but thing is now Shugoki and Warlord have lost one of their best tools. I feel like assassin's feats are overall better, the nailbomb still takes your whole health away and sharpen blade can kill you in two or three hits, Fiat Lux doesn't deal damage anymore so basically it's now a Kiai, one that's way easier to avoid.
Also I feel like assassins get more preference over heavies, like a Shinobi's kick, a gladiators shield punch and a shaman headbutt will interrupt "uninterruptible" attacks with hyper armor like Warlords or Highlander, which is way inferior to Berserker's hyper armor.. an assassin. Come on guys give heavies some love!
