Imo, nothing. Just like any other game that introduces a new class. The other classes have to learn how to beat it. Takes time. It'd probably be easier if we had a dueling system to assist in learning the quirks. Example: I used our flaming dash a few rounds in crucible and by the erratic behavior of the other team and my own, I think they were beyond surprised I could even do that. Or that I didn't throw any hammers and just charged in hardcore style. So IMO, nothing till it's completely understood.
