Personally I plan on using the new engine mechanics to try out the possibility of "Heavy Fighters", 400-500 ton craft with with medium armor and probably a railgun or meson cannon. It wasn't possible in the old system due to fighter engines being limited to 50 tons, but I think there's potential there. Particularly since the larger size and armor should help against beam fighter's primary weakness, AMMs. Basically, instead of precision strike weapons I'm going to experiment with making mini-warships that make use of their carriers to have high powered engines.
Mesons would be better against ships, obviously, but railgun armed fighters should have superb anti-missile capabilities due to getting four shots (equivalent to a pretty high tech gauss weapon, and 200 tons instead of 300 for a 100% accurate gauss). I plan on experimenting with both, or maybe even going with a mix.
