Not really. I have seen a lot of them waaaaaaaaaaay up there of late, but killing them is no particular problem. The minor problem I might have is the alt they can achieve, but that is a play concession I can live with.
What I don't like is the act of taking 5-6 of them up to whack every fighter hangar in 12-grid area. It isn't because I think it is an unfair tactic, I just don't personally have the time to chase so many to that alt and defend bases. If I have that 45-minute time limit, you can see where this can be problematic. This is more my limitation, and if that is the way guys choose to play, it's their money. I just quietly log off, as I know there is no chance for me to fly a fighter and fight in a reasonable amount of time (read, if I have to fly 3 grids to get to a fight, I ain't staying).
More power to the strat guys who want it that way. I simply leave and do some more work. I might pop back in in a few hours and try again, I might not.
