I personally often recommend Heatsink and Lochnagar over Greased for my gunners on Hades and Lumberjack. Rarely do I need Greased on any of my guns. I had it sometimes for the Gatling though, especially if the gunner had to use Hades and Gatling on the same ship.
I would personally say that Greased Gat's range was a bit too forgiving for the gains it had, but I hadn't tested current Greased Gat too much so I wouldn't know if the jitter increase was too big. Carronades always had trouble with jitter and if you don't bring Heavy or Inc in special cases then you might as well not bring the Carronade at all. Greased Banshee used to be able to still hit relatively easily at its maximum range, so I am not against Greased increasing jitter. Is it too much jitter? For some guns it is, for some guns it isn't. Change jitter on Greased to 50% or change jitter on guns? +50% jitter on a gun with 2 deg jitter is a total of 3 deg of jitter, is that a lot? Does it make a significant difference? I don't mind seeing it in dev app after the upcoming patch.
I personally haven't seen most people complaining about the changes here in the dev app testing sessions, so I don't think arguing against the testing process is justified. Constructive feedback to help it get better I won't argue against, but don't be against it unless you tested the testing process. In my opinion, what we got here is also better than what the Muse developers themselves have given us.
I am a bit biased towards the current testing process, because I have seen this game sit in a state of "Why are the devs doing what they are doing?" "Are they listening to feedback?" "Does Eric play the game?" for a solid 4 years now. How long did it take for the Mobula to be nerfed? Remember the seemingly out of nowhere Spire nerf? Pyramidion is still suffering from its first nerf a few years back. Had it not been for the testing sessions, then the Heavy Carronade would still have no arc in any direction and Heavy Clip would very likely still be worthless on all guns. The current way of getting changes into the game feels much more active and much less random despite the lack of professional testers, which one could argue Muse should provide.
Got objections to changes in dev app? Voice them, there is a dev app section on the forum, you have the trello, you have Discord for more active discussions, email and even surveys for each test session are being set-up for more organizsed feedback gathering.
Want changes brought in to dev app like for example testing +50% jitter increase on Greased isntead of +90%? Voice them?
