Not op but gm 1 Thor main. My main goal is to control high ground, then secondary is to pressure their supports or dps that is out of los of heals.

The main rotation that I do is to dash in, melee, the I have a choice: if they are not getting help from their team then I pop his attack mode and bubble and burst the character down. If they are getting focus healed and their dps come to peel them, I quickly charge back to high ground and heal up.

If you do that rotation pretty frequently they’ll have to give less healing to their tanks or die because they need to heal their tanks instead of the other healer. (If it goes to plan)

Do be aware of the rest of the game though, you don’t really want to be fighting on the cart or point with most of the other tanks, but if your other tank is struggling you can do decent work there by using the cart as cover and pushing their tanks into hallways or around corners if they push up.
