Not immediately, no. But give them two weeks of bootcamp and they are fine. Especially since a lot of them have played VAL at some point or play it casually on the side every now and then, it's not like they have never touched the game.
And I mean the same can be said about util in CS. There are always new smokes, new executes etc being worked on. Going back to CS because you used to play it competitively like 2 or 3 years ago in Tier 2-3 is not as big of an advantage imo.
But overall I agree, teams would smash their opponents in their game like 98% of the time, so it's kinda pointless to even argue about it.
