To be honest, I find the the Adapated MACO three-piece bonus to be underwhelming, and I don't find the MACO engine to anything special either, so I dumped the MACO engine on my Fleet Rhode Island and replaced it with an Elite Fleet Engine, which I, personally, much prefer - and I still get the (adapated) two-piece bonus.
I mentioned this a while ago but cryptic answered that the engines are still powerful.
And yes, the engines are powerful.
But useless in sector space.
And cryptic reiterated again that the engines were still powerful.
I guess "situationally powerful" != "powerful" to me
besides from anything above warp 10 is rather unrealistic and slipstream should be slightly below that (if you can even measure), no one should even be able to fly warp 10 the whole time but have a cooldown on it (=>transwarp?). whats the matter of sector space if you can be everywhere in no time.. well.. i cannot answer this question either.. i dont like sector space at all. i would rather be in somekinda space all the time like in freelancer.. not having to switch to other instances to actually fight enemies. but thats just me (and probably a few thousand other captains)
