Should you just swap into tank comps?

Newer league player I’m feeling ready to get into ranked and pref Viego

I have a 75% win rate in drafts rn but people just don’t seem to play tanks at all when they’re messing around so I have no practice into it.

My first 3 ranked queues so far has been stacked with bruisers/tanks. Recent game was Malphite/swain/trundle/yone and even tho I was massively ahead of the trundle I just couldn’t do anything any time that meaningful when we’re 5v5

When is see that should I try and go trundle/amumu/voli myself??
