What do you think about K2SO's viability?

K-2SO is a good character when played well. He can be frustrating and annoying most of the time since he taunts randomly when he attacks even if he has very low health, resulting in him getting killed frequently. Otherwise, he could be very useful in the Arena. He can be annoying to opponents considering that he always taunts when he attacks, making him a good defender for the team. Plus, he also counters and his special ability can be handy against opponents. However, he doesn't have the best health that he can offer so you must manage him carefully. I recommend you not to upgrade his Enforcer ability because that's where he is excellent at getting himself killed.
