Suggestions:
HT rampdown: from 1 sec to 0.5 secs. This is the original number i suggested back when preview 1 was being discussed, i think it would make HTs responsive enough while still making them be distinctly less agile than the smaller thrusters
Standard, Large, and Boost thruster rampdown: set to 0. it's just not really necessary to have rampdown on them, tbh
MRT thrust: increased by somewhere in the range of 15-25%. MRT's rampdown and overall maneuverability feels about right to me, but it is struggling in competitive gameplay, i think this would allow ships to have lower investment in MRT for the same benefit and be able to actually afford other thrusts for turning purposes
Boost: after boost mode finishes, require boost to be fully recharged before it can start producing thrust again, sorta like shields. would maintain boost's power and agility while boosting, but give more consideration to their intended downside of having downtime, in a way that doesn't punish good logistics
TB: hopefully the thruster changes would make fighting against TBs reasonable with the 20% thrust nerf, but in case it doesn't, nerf TB's cost rather than its force. an increase of 5-10k (in steel, hypercoils, and possibly hyperium) would have minimal effects on career where such resources are relatively plentiful and cost isn't much of a factor, but reduce the ability to have loads of TBs while still having a load of other stuff
