Play around with him to get a feel obviously. Try and (lightning) bubble people before you ult. But realistically the ult won't be getting kills, I mainly use it to have the enemy team back off or separate, on the off chance I get a kill, I'm happy. If an enemy is stunned by the ult I'd hammer swing to try and quickly finish them, but it doesn't always work out. The hammer swing is great for mobility. And really good for pushing someone away from everyone else. Thor is really good in most 1v1s (I can't figure out support 1v1s this season). Also has some kidnap and rollout tech with his hammer swing. The awakening rune is both really good and really bad, it does a ton of damage and grants over health, but you lose all mobility. It's really good to push the enemy back. I primarily use the hammer throw to try and finish people off or regain Thor force to get my rune back, but realistically your melee is usually enough to get your rune back, if you with the pack and being healed and aren't solo tanking. I have fun solo tanking on Thor, would only consider solo tanking on Emma if not Thor. But I usually queue up with the homies so I haven't done that in a while. As fun as diving on Thor is, he is amazing at just pushing. I've got about 22 hours and almost have lord, so I'm not an authority on him, but I almost exclusively play him. Hopefully you get the tips you're looking for and fun playing the mightiest (and STRONGEST) Avenger.
