Vel'Koz True Damage a bit to much.
Despite the crucial fact that Vel'Koz got nerfed in this patch and the crucial fact that his damage did take a hit, i still find it extremely hard to battle against Vel'Koz. Every time there is a vel'koz on the enemy team it seems like team fights become impossible, he has a lot of AOE and a great AOE, CC ability that all proc his passive that will start to do true damage, then his ultimate which seems to have under a 60 second cooldown is up every single time you team fight and it also does true damage.
The fact he does so much more true damage than any other champion is really frustrating to play against and is making games against him extremely stale and more often than not a bit one sided considering you can't avoid the inevitable 1000+ damage he's going to do to your entire team.
