Dusekkar is weak, here's how to fix him (image unrelated but would be a cool rework for two time)

You have to be pretty good at aiming and tracking to make sure that you hit the plasma beam, yet the plasma beam does nothing, I thought dusekkar was gonna be a sentinel, not a support, here is my suggestion

Make the Plasma Beam stun for 3 Seconds, along with the slowness II buff, increase the Hitbox and have some sort of lock on (or maybe have it stun for 1 second but shoot in a burst of three)

That's literally it, just make him better, he's weak, he hopefully will get a heavy buff in the next update, along with his XP gain when using abilities, it's hell to level him up to level 25, this would make him more fun to play and better to manage
