Yes, you should feel bad about calling in an additional two gunboats in against two snubs. I'd personally call that a gank. If we have the people to rely on for bot supply, and you don't, then how about accepting a loss?
What Dane said. Hell, if I was in space being shot at by someone who wanted to kill me, I'd be wondering why the battleship itself isn't defending me (and isn't able to obliterate the target in seconds) or why I can't simply dock aboard safely.
