The buff damage does seems a bit more than is needed, though I do not see it abused too much. Maybe it is just in comp games, or I just have not been on long enough to run into it as often. Most crews I see have a gunner, so I do not understand where people get that gunner is not used. The only times I don't see a gunner are on specific builds or ships, like the mobula or squid, where a gunner is not needed too much. Really just like anything that is class based, sometimes you will not need certain classes. Does not mean that a class needs buffs, or is unloved. Adding more damage to gunner, or removing the buff effects on buff engines, will not make a gunner more useful on a ship that needs three engines. Nothing wrong with it in my opinion.
