Messed around with the Blueslaught a bit this afternoon. A few things about it are bugging me. For example, here's a comparison of the base Onslaught, XIV, and Blueslaught with similar loadouts--
The location of most of the turret bases is unchanged from the base Onslaught/XIV sprites -- yet the locations for some of the weapon sprites are subtly different. Some of them have had their firing arcs adjusted, but that shouldn't change the center point of the turret... and others have the same firing arcs but have still moved a bit, like the centerline medium and large ballistic mounts. Was this intentional or an oversight? It's a very minor complaint, but unfortunately bugs me a lot now that I've noticed it. Can't unsee!
The deployment cost also seems a bit high. While it offers a fairly unique mix of direct assault firepower and fighter bays, it doesn't seem to deserve 50 points. In AI-controlled sim matchups, the Paragon consistently beats it, while the Odyssey and Astral can fight it to a standstill. While I agree it should be higher than the base Onslaught or the Legion -- both of which it can quickly kill with a good loadout -- 50 is probably too far. I'd suggest 45.
I'm not sure I like the changes to the side Large Ballistic mounts. With both of them more forward-facing, it very quickly runs out of flux, especially since it's been lowered from the base Onslaught's capacity. This isn't so much a problem when flying it personally, but in AI hands it seems to run up its flux a bit too fast. Outfitting it with low-flux weapons like Hellbores helps a lot, but tweaking the turret arcs to be more similar to those of the original version would help as well I think.
Quite a lot of fun to play with though. Good work!
