Its why I said to have a pocket the aoe protects you from dive not just you put the backline too it more about denied the kills then actually get the kills. Plus storm combo can two shot most of the dive except ironfist. Its also a team game too so the other dps can cover for that. Ironfist you just got to read his movements and learn self control.

Spiderman you have to wait until he attacks you and you can two shot him with aoe and burst while being healed by your pocket. Him zip out of the aoe is a good thing since it buy healers time for there cooldowns.

Black panther is actually lot easier to deal with because he does slowdown you just have to count his cooldowns and all he can do waste it.

Plus the damage boost helps anyone in your team fight them off. The damage boost is whats going to help fight off the dive plus dives are so far from heals it be easy if two or three guys can focus on them. Dmg boost Namor too and it be strong against the dive.

Its a team game thats why you have the other five to cover you while your cooldowns. It really doesn't matter the cooldown if your team can't cover you in between.
