most bs do.
a Mach with a t2 500mn goes 1500 m/s. While it is no issue to be slow when going with long range ships, which have very high projection, it is just not acceptable for ships that are supposed to get close and personnal. you will get evaded by frigs/destroyers. you will miss cr too close.
with 100mn you can’t dictate the range, can’t force the frigs into straight line; can’t burn through the gate; can’t split the frigs from the cr to take your time shooting them.
100mn are very good. When you don’t mind completing the mission two DT after taking it.
