It also has a cool down and can get screwed by sprint lock,also shoulder charge like I said you can't shoot you are literally running into someone majority of the time shoulder charge isn't that hard to dodge or gun them down where as wombo is near impossible.Yes wombo uses abilities but that doesn't change the fact it's a 99% of the time a guaranteed kill.

8 seconds is a long time to find a target and charge them in these small maps.
