More roamers to expand my roaming pool

I currently main grock. I’m hoping to learn diverse heroes. I was thinking heroes like hylos, kalea, (tank) Chou, and possibly diggie and faramis incase I can or have to support roam.

Any hero recommendations? I’m mythic honor, and I don’t care about dmg or how much I can solo carry, mostly just how much I can provide for the team
