The PvP fan base is trying to claim prismatic needs to be excluded from PvP because it's going to break it. Really? Aren't you the same ones claiming that the abilities they've chosen to be a part of the subclass are trash? "But they buffed the abilities specifically for prismatic." No, they made them synergize better. They won't have increased damage in PvP. "If they synergize better, they'll have more up time." Right, in a mode with abysmal ability regen to begin with. Oh, and didn't you also say they were trash abilities to begin with? Theoretically, you should be able to run a pure subclass and use your good abilities and get just as much up time. I could see an argument for prismatic being pretty hard to read in a crucible match. A subclass that allows your enemy to use abilities from any of the subclasses would definitely be a wild card. I don't necessarily see that as a bad thing though. Tldr, I just think you're blowing it a bit out of proportion. I would be more worried about those new exotic class items if I were you.
