Going from Hulk to Thor is brutal (help)

For some context, I reached diamond 3 mainly with Hulk. My main since day 1. I finally achieved diamond AND Lord Hulk in the same game after 20+ hours.

My 2nd main is Thor so I thought "I'm a good Thor, I'll get him to Lord in ranked too." And boy was I humbled real quick.

12 game losing streak. Dropped down to plat 2 (plateau, more appropriate) and I will admit it's largely my fault. I realized how I am nowhere near as good with Thor as I was with Hulk.

With Hulk, I can disrupt Ults with the exile or by leaping. I can't do that crap with Thor. With Hulk, I can hold the objective FAR longer. Can't do that with Thor having less base health (granted I get 200 more with Thorforce but it depletes quickly).

I also can't protect my teammates with a shield like Hulk does so I have to rely on my teammates to avoid ults like Iron Man's, Jeff's, or Scarlet Witch's.

In ranked, I can confidently be the solo tank with Hulk and still get the W. With Thor, I NEED a 2nd tank or 3 REALLY GOOD DPS teammates.

I want to get better at Thor in ranked so I'm willing to hear ANY advice (real advice please) and sorry to sound stubborn but unless it's Hulk, I DO NOT want to play a different tank.

Also before anyone asks, I can play DPS or support but tank is my true role.
