I was just looking at that list. I don't own one, so in an unbiased way I don't feel what they're doing to the M50 is a bad thing. It should have reasonable power limitations in terms of weaponry with such large engines on a small ship. I wouldn't be mad at the same limitations on a Merlin.
There are a few parts of that I wouldn't have issue with. It makes sense that the M50 would have high power draw, but
also reducing the strength of the M50 powerplant doesn't make a lot of sense to me.
The M50 can only mount a pair of S1 weapons, which means it is already extremely limited in firepower to begin with.
The Merlin, on the other hand has a killer high DPS baked-in S2 along with a pair of S1s. It's also relatively fast.
I wouldn't have any issue with it if the M50 wasn't labeled and storied to begin with as an interceptor, which should historically at minimum have enough firepower to significantly delay incoming threats. It started out this way with a pair of S2s, then that was nerfed, and then the handling was nerfed, and now the powerplant is getting nerfed.
If it ends up being nothing more than a mediocre racer (the 350R is faster and beats it most of the time anyway), I'll probably just melt it.
I don't want to, because it's a still a blast to fly (and look at). I just don't have any use for a race-only ship.
I think the real issue is that CIG needs to decide what an interceptor actually is, and consistently equip ships with that designation to be effective.
