I disagree with bringing back hyperthrust, with the barrel roll system you actually have to do something to earn your little speed boost hyperthrust on the other hand is an easy, lazy and simple push of a button for instant speed, you can't possibly do it wrong and pay a price for unskillfulness can you? Then theres the system itself, currently I believe, assuming no energy is absorbed a Triakis could pull off more barrel rolls then lets say an Icaras due to shield strength however there are only limited tracks where a Triakis/Tigron could really exploit this system. Assuming it was implemented the same way hyperthrust would give a huge unfair advantage to ships with the highest strength shields since they could boost for much longer around the track and just like that you have the issue of superships and an unbalanced game again
