You guys are sleeping on Black Panther.
I think he's one of the top melee characters in this game. Only Magik is better. If you count Psylocke as melee she's better than him too. The only character with better movement is Iron Man.
I play on PC so I'll use the default binds for moves:
You don't even need to aim with his spear. You can shoot the ground and the splash damage will hit multiple characters. Don't spear spear. You want to do a melee combo. Only use his left click if an enemy is in the double digits.
When you use the SHIFT dash it refreshes when it hits people with a vibranium mark. You also get a shield when this happens. Use this to follow up a spear and to get bonus health if you're low.
His E dash will go towards and give people a Vibranium mark. You can also use this move to make your retreat.
For example you can Spear>SHIFT>SPEAR>SHIFT>E>SHIFT>SHIFT and use E to get out. You want to finish people off
get in fast and get out. You also want to pick people off that are by themself. Wall climb and use his double jump to stay out of vision. If you go in 1v6 yea your gonna die, but if thee enemy team is also fighting your squad you can get in there and kill people and escape before they know you were there.
Storm is hot ass though.
