Not really true. Unlike most of the veterans that specialize in one type of ship and loadout I'm competitive in many different combinations.
Choice of ship and loadout depends on who I face and what ships they use.. and I can switch to a different loadout with no problem whenever the situation in the arena changes.
Other players don't seem to have that flexibility.
Are you denying the fact that Silent Running is easily the most OP utility you can have?
I don't begrudge you using it, it's there to be used. But I do think it should probably be removed from CQC as a whole.
