I think a title at -2 points puts the Defender in a good niche for most squadrons. That said, I think x7 is maybe a tiny bit too good; personally, I would've liked to see it give a free evade action, rather than just a free token. That way, the opponent can actually play to counter to some degree. As it is, things like stress just don't concern defenders very much.
But if it were a free evade action, you'd have the problem of not effectively being able to bump the suckers, since they could go fast, bump, then trigger the free evade action to proc PtL and barrel roll out of the bump. It would have been pretty mean. It had to be a token.
Oh, good point. I did not even consider that.
So to revise my earlier stance:
I wish the title read "After executing a 3-, 4-, or 5- speed maneuver, if you did not overlap another ship or obstacle, you may perform a free evade action."
Part of the reason that defenders are so good is their ability to ignore things like stress and bumping, which are usually key to reigning in aces. And that's fair enough to a point; it gives them a nice niche in Imperial lists. The problem is that they do that already, without the title, simply by virtue of having a white K-turn and six hit points. At this point, they really seem to fly like sledgehammers more than anything, and I'm not a huge fan.
