Don't look at it as outnumbered, think of it as a "target rich environment!" Heck last night I was in LW Orange and the Bish were hitting A10 hard with the fleet. I just grabbed a little higher, hit a couple buffs and then BnZ'ed (or cherry picked) a few fighters until the base was captured. It was loads of fun!
Why was it fun? because I knew that saving the base was not an option. With that knowledge I just said the heck with it and grabbed a few kills.
When the horde comes to play you have to switch the wetware over from the testosterone driven neurons to the common sense neurons. Use your alt and speed to pick the proper target before engaging. Hit and run becomes the name of the game.
