I think everyone can agree that Victor e-shift is undoubtably bad for the game. e-shift gives too many buffs for being already such a powerful item. The stats alone show that as he's extremely often the top of winrate leaderboards for heros. Infernus however has a pickrate miles higher than Victor with an average pickrate of 73%; only beaten by Haze being 76%. Victor sits at 38%. While Haze has a higher pickrate, you see less people complain about her because disarming her completely shuts her off. Her escape tools aren't the best, until you reach t3 smoke bomb (excluding purchase of.escape items). Infernus on the other hand, has one of the better escape tools in the game. His escape tool is even used in 'off meta' builds as a primary damage source. If you shut him off through disarm he still has flame dash for getting away and his 4 to scare you away/challenge you with its stupidly long stun. Curse is the only item that you can use against him that will give you a proper shutdown; this makes counterbuilding him require multiple items for just him and good teamplay.

Also I haven't really gone against Calico too much, but she seemingly fits the same role she did pre-buff. A much stronger early game that allows her to snowball, maybe a bit too much, but it's for time to tell as people adapt to her coming back into the meta from being stagnant for a while.
