Vladimir's Pool
Hi there, I just had a game as Vladimir whom I picked into Fizz since that used to work out quite well in early game. The idea was countering Fizz' ultimate with Vladimir's Pool, which is possible even when you're already hit. Well, used to be possible would be the right thing to say, since it didn't in said game. In the game, when I got hit by Fizz's ultimate, I thought to myself: "well, I know what do". And I did my thing, but unfortunately something changed, namely that I received the knockup and the damage while being pooled. That was new to me since it always worked before, so I assume that's a bug, since a can't recall a note in the patches.
Another incident was, but that's already a long time ago: I once pooled in order to dodge the damage and the silence from Cho's Scream, and the following happened: I received the "silenced" bubble while being pooled. So, either I dodged that, which means I can't be hit since I'm UNTARGETABLE, or I had been silenced in which case I wouldn't have been able to cast pool in the first place, but not both.
So maybe that shows that you guys should look into that ability again.
TL;DR: I received damage and knockup while being pooled with Vladimir from Fizz's ult, which shouldn't happen since the champion becomes untargetable and because that didn't happen before. Please check the ability.
