Thoughts on this team comp?

Seems fine.

But what if the enemy team counter picks you with whatever.

You shouldnt have a set team comp that you go to, unless these are specific champions that you 5 man with and you all main said champions.

Basically all you need to know is your team comp should be rounded with CC, AP, AD, Range, Melee, Tanks, Carried, etc.

I prefer 2 ap, 3 ad, 2 tanks, rest moderately squishy.

As long as youre not running 5 man ap team, or 5 man ad team and you bring some cc and tank to make things less awkward, anything is fine.
