Nah, stuff is way more complicated. We now got more strong heros, thats fine. For the upper class and balance in general, this is favorable. It only sucks if you enjoy playing the low-tier heros. I mean Shinobi isn't worse then PK or Valk, just different. But Centurion loves crushing the lower tiers. His punishment is insane and he can nicely open up too. And you can't really use range to your advantage due to him charging his heavys. So wiffing attacks into something useful is very dangerous. Though thats true for Shinobi too.
If you enjoy the upper tier however, you got plenty of tools. Assassins are well suited against Centurion. Warlords can trade efficiently. Warden can use swift attacks and his 50/50. Valks swift attacks work well too. Just to give a few examples.
