6C not having a pistol-gripped weapon just feels so weird to me.
That's something that's actually bothered me about not just the BattleMaster 6C, though I'm semi-accepting of it because we've seen forearm-mounted PPCs on Unseen BattleMasters occasionally as far back as FASA's invasion of Luthien sourcebook.
On the other hand, there's the new art for, say, the Wolverine and the Wasp, that continues the trend we saw in Project Phoenix of dropping those handheld-style mounts. Even the new Phoenix Hawk and Griffin are much less pronounced in that regard.
OK, on the new BattleMasters themselves:
I seriously dig the BattleMaster C 3. Very straightforward conversion. I like the banked light PPCs of the BLR-6G, and while I'd prefer a standard engine, can live with a light engine. The BLR-6C is a great homage to Rolling Thunder, but really feels underwhelming in terms of actual firepower.
