that reason is invalid for twitch's comeback
easy answer is that twitch is a hypercarry, even if tanks arent popular he will still have a godlike kit
but the only reason twitch isnt as popular is due to his weak early and weak mid game (nerfed)
enemy jungler and the agressive bot lane comps make twitch backfire too easily as a pick
the sole fact that enemy has a tank instead of a fighter does not change anything for twitch
on the other hand vayne is the one who can be happy, since tanks wont duel vayne so easily meaning she gets to reap the benefits of her kit easier
also sivir who can be resistant to engages comes to my mind
but under any circumstances i dont see anything that twitch would benefit from
