Nah, it not that black or white.
I mean yes, his teammates do not help. But his lurkings are each day less and less impactful.
First of all, because his playstyle is so static that every team(specially tier1 ones) ALREADY KNOW that Bennie is lurking on their back....doing the same thing over and over again makes you predictable.
Second, I totally agree that having Buzz and Altekz being the ones that you relly on activating your lurker sucks....but there are tons of rounds in which one of his teammates makes it to win the opener, and he still is just static, waiting for the rotations to be on his crosshair and that's it...this can specially be noticed on ancient, where he tends to lurk mid, and tons of times cts rotate from donut, and he never even takes a quick look at middle.
Guy is a turret as lurker, and turrets are predictable.
