Well you are entitled to your "opinion" but as the airframe was designed to loiter far offshore then dash and launch at either incoming sov bombers or cruise missiles it did it's job perfectly.
Well just a couple of points... it never had to launch at an incoming bomber so we don't actually know if it "would" have been perfect at it's job but as I said originally, it didn't have the flexibility to perform outside that cold war "loiter" role. The GR1 had a low level cold war role but was able to perform different roles at different altitudes and to do it very well.
