Thor is the Norse god of thunder and the son of Odin All-Father, ruler of Asgard. He wields the mystic hammer Mjolnir, which allows him to fly and fire bolts of lightning.Marvel Source
Thor was a founding member of the Avengers and frequently battles as one of their number. At times, Thor has used the secret identity of Donald Blake to walk among mortals, but he always returns to the halls of Asgard to hoist a tankard with his fellow gods.
Godblast is dealing a lot of damage, but it is in no way OP.
You will see these huge crit numbers but you also have to keep in mind the cooldown on it. So it is not 50K dmg every second but only 8-10k on crits.
Rotation is basically to use Storm Strike to generate Odinforce, either kill trash packs with Godblast or use Asgardian Frenzy.
When in Frenzy it is still enough to cast AF again with one pip of Odinforce to keep the 6 Pip effect.
Use Storm Strike to regain Odinforce or Hammer Strike to regain health with AF active.
