I feel like since they were going for the "jack of all trades" approach they felt that the stances should be relatively weaker due to the fact you can swap somewhat frequently. The reality is that you just have three mediocre stances and a job with no real place, and the ability to change stances isn't a real gain. For starters, you are encouraged to hit DnJ on cooldown for the Powder Barrel for more DPS/Utility, so the freeform stance swapping means nothing. If anything, they should remove the Powder Barrel effect so you can really have it on standby for an emergency swap if needed. Not to say the stances are necessarily a bad thing, they have their place, it just needs to be buffed and tweaked. There were a few times in my over 500 matches where I would say be in DPS stance(the only really viable one at the moment), and would intentionally swap to Tank stance when I needed to stall or hold the point. So the playstyle can be there, it just needs to have more of an impact and perform less janky.
