Probably phase prism, the idea of swapping yourself with an enemy is amazing to think about and really shows off skillful Artanis players, not only landing it , but when to use it.
As for the hero part i thought of a concept a while ago for zenyatta, but a concept i do want in the game is a hero which acts like a mount for another hero, so you would be able to ride this hero, but they would go slightly faster than the average mount, weird but interesting IMO
I believe in spirit entity, like a dead person still has a conscious to watch over me and smile or cry at my actions, but as for ghost that just scare people, i don not believe
Me i am GuardWizard, if you are asking where i came up with the name, it’s just the fact that i love being the Tanky guy for the team, So a giant Guardian and a wizard guardian sounds really cool, hence GuardWizard
Both are good in thier own right, you should pick anubarak against a bunch of squishy mages along side a diver like illidin
As for arthas he is great to protect backline, while he has no stuns he has increadble sustain along with slows and roots, i would pick him with a high burst mage or hyper carry like valla or ZJ
Neither of these tanks i play a ton of so take my advice with a grain of salt
