An out of context clip does a lot to boost the popularity of a youtuber/streamer (and apparently sway the minds of the public), but does nothing to prove your point.
Link me a video of pikaboo queuing into r1 teams and "deleting" them multiple times with no counterplay available. You won't be able to. Feel free to watch cdew,, flop or minpojke (these are the three I've personally seen, but I'm sure there's others you can watch) queue for 8+ hours of skirms and successfully surviving through this supposed attack that has "no legitimate counterplay."
Is it strong? Yes. Is it *WAY* too early in the expansion to tell if it's legitimately OP? Yes. We need more gear and meta analysis before we can do that.
