That's not an excuse by any stretch. With Arena Commander, they've had a playground to test-fly ships. For two goddamn years now. Any issues, whether it's algorithmic complexity, pure game mechanic decisions etc. about the general flight model, could've been and should've been ironed out in that alpha test software piece. Including whether or not they need to rethink the gimballed thrusters for ships. It simply hasn't happened.
I agree, no excuse at all, but remember, we don't understand the flight model, it's sooo realistic and awesome, it's seen as being bad! ...
