As far as fighting moves go, jorms moves can be predictable but the punishment from being downed is high on top of the added shield the strike gives. Getting a shield from an attack is op in my opinion. The jorms hammer slam feat is cool but is hard to avoid as the engagement with them is commonly in close proximity. The feat is uninterruptible too so attacking them to avoid the feat is out of the question. The jorm is a solid character to play which is why a lot of people play him/her. Other characters such as the ninja fall short when compared to the combat abilities of the jorm. In short jorm May need some balancing tweeks.
I know this has bean said a lot but a stamina bully is not a good hero for the game it basically makes it so attacking is not encouraged jorms offense is basically wating for the enemy to attack wasting any stamina at all is beneficial for him unlike other heroes getting you on the ground is easy for him I get that those were the tools you gave him but they are not fun to play against he si not good at 1v1 but in team fights he is to strong the healing with his bashes sould be turned down and I know that the bashes dont garanty anything but there is no punish for missing them the all come together to get him a 40 damage hammer slam also making it harder to do anything after he lands a couple since you are already low stamina and getting any lower by trying to fight back is counter productive and the stamina regen paus is absurd is still like 2 second or something while most heroes don't have any
