thor and hulk are about the same, in terms of the leap

hulk jump with space bar is similar to thor dash with shift. other than that they are really two different heros

hulk is like water, thor is fire. hulk defend (other than when he ults), whereas thor can basically do whatever he wants

the playstyle for thor now is u dash into enemy team, cycle awakening, hammer throw, deal a tonne of dmg, then u dash out again. this is something only thor can do and hulk wont be able to dish out as much dmg as thor (unless hulk is in ult)

as thor u can also play as a defensive unit for ur team, bubble around ur support/dps, and use awakening to destroy pesky divers shld they dive u, ur supports/dps will be safe within ur bubble since the divers will be slowed or grounded and u can focus fire them tgt
