Like seriously:
-It doesn't have enough bullets in the clip to mitigate the low per bullet damage.
-It's got poor bullet spread so you can't get consistent headshots to do a little bit of extra damage (which it sorely needs cause its damage per bullet is lacking).
-Its reload speed is too slow for the for what little else it does.
I really like playing Mikah but then I remember that her primary is bad and that her ability takes way to long to recharge if the decoy is destroyed. Id would prefer that the spread bloom would start later and that her clip size would be increased by 4 so she could do more consistent damage. Her other guns could use buffs too. Mikah just underperforms in comparison to everybody else's weapons.
