I think the real problem is combining the accel GA plus the reduced mass results in the 40%+ increase in acceleration. The reduced mass itself leads to a 25% perk to accel. This is exacerbated when you look at TF exp, where basic ints (using booster 1) have an accel in excess of 86. Adding in accel GAs push that to over 100. Even lagtastic EoR ints had a boosting accel less than 100.
Combine that with TF ints' slender profile, people tapping booster keys, and laggy servers....and you have this thread
Bios ints have reduced mass that (eventually) results in an accel profile similar to TF ints, but Bios ints also have a MUCH more generous hitbox and frequently mount heavy cloak in lieu of the sweet accel.
