With how they've reworked the Ranged DPS roles in PvP to play more of being at a distance, Bioblaster is a really big offender in the general theme of how Machinist functions in PvP in my opinion. I think the only time I pair Bioblaster is if I know Wildfire is up, so I can waste it ontop of Scattergun and then run off to safety then go back to working up heat stacks.

And like sure, Scattergun exists but that seems more of an emergency 'get away from me' skill which fits the class, but Bioblaster invites you to get within the danger zone of other enemies to dump a very underwhelming DoT onto them ontop of wasting a charge to get onto the actual useful skills of the rotation, plus the 75% heavy generally isn't worth the charge of Analysis either. It feels like unnecessary bloat.
