The ambusher is in a bad spot
Almost nobody plays this class, and for a good reason. The backstab mechanic isn’t really worth it since it’s pretty hard to trigger while the damage output suffers from a lack of 2 handed weapons. The class also doesn’t have access to shields or dash cooldown reduction or other stuff that could help him.
I don’t think the class should have access to big weapons or MAA abilities, but extending the backstab angle would be a good way to make this class more viable. The throwing knife damage could also be boosted a little.
