You know whats weird about the Malzahar and Vladimir reworks?
The fact that they somehow hilariously made both of them even more toxic then before
Vladimir heals way more now,in lane not so much but in fights he just gains chunks of HP which is way more then he could ever do with WoTA,His E hurts absolute tons and its also REALLY spammable,He can also be pretty darn Tanky with tons of HP even if he doesn't build 
Malzahar,okay imagine his old self as Space Aids,now its "extra dimensional Aids" , overall he isn't any more fun if not less fun to play against post-reowrk compared to pre-rework ,His minions push the lane harder and if his E just randomly bounces on you your just going to take so much damage thats so hard to really stop early on,The fact that he can keep a PERMANENT E is even worse(if you don't know what i mean try Mal with 45% CDR),His ultimate in a small way is actually worse and better,worse for burst kinda DPS(generally better against tanks though),but better because you don't actually have to channel it to do dmg so I'm kinda 50/50 on that
, need me to go on?
