Wasn't the Avenger just a modified version of Vader's Advanced? I think it has a lot in common with the Advanced.
Those stats make sense but are you really going to take a generic at 25 points over a RGP w/ PTL? Or bring out a named Tie Advanced pilot? It would be just another option in the 25-33 point range which the Empire has a lot already. You are going to make the Defender even more obsolete.
4 agility would be nuts as a stat stock.
No, the Avenger was a different branch of development as far as I've been able to find. The Advanced, Avenger, Interceptor, and Defender were all experimental branches off the base TIE Fighter model.
I see the Advanced as a more direct improvement over the Fighter (primary attack force), the Defender as a more direct improvement over the Bomber (heavy hitter that is tough to kill), and the Avenger as a more direct improvement over the Interceptor (dogfighting superiority).
As for making the Defender more obsolete, I was originally thinking of making the Advanced the same cost as the Defender. At the very least, it should probably be at least 26 points so you can't take more than three in a standard squad. I don't know. I don't play competitively, so I'll leave the cost determination to someone more experienced.
