I don't see why a guitarist needs to improve to be in the top 5 guitarists of all time. Did Jimi Hendrix improve? How about Yngwie?

With Gilmour, it's never been about his technical prowess, it's been about his phrasing, his soulful bends, vibrato and so on. No one has ever claimed that he's the fastest guitarist of all time - but that's not what this list is about. How can anyone, including Gilmour, improve on his playing? I don't see what there is to improve upon. Maybe you can help me out there.

What's wrong with Gilmour in the top 5? He does more with 8 bars and 20 notes than many other "top 5" guitarists do with 2 minutes and hundreds of notes. Isn't that the mark of a true artist? Someone who expresses himself through his medium in a unique way? If that isn't the standard and great guitarists are expected to be speed freaks who abuse the harmonic minor scale, then Gilmour fails and Yngwie wins. But if it is, I'd put Gilmour in the top 5 without hesitation.
