I don't want people to focus on Makutu so much that they forget him, so here are some things I thought of:
-Higher base attack damage
-A bit extra shields from attacks
Shield power, thing.
I have two ideas
-Increased shields depending on the number on surrounding enemies
-Increased damage and shield gain based on the number of surrounding enemies
Jumping Move where you jump, and move
-Wider radius, maybe like a 50 percent increase
-Tracking could be good but it could also hurt his ability to escape
With his immortality ult there wouldn't need to be any changes
His overload could use either a damage buff, or it could apply a slow effect so he can hunt people down better
I feel like the changes I list would help his survivability, and his capability to disrupt groups of enemies.
