No flips for you!
Sounds like the problem was over-reliance on reducing the character's hit points by way of attack rolls, rather than the doesn't-actually-apply-against-everything benefit of blur and plate armor.
Actually, the problem here is that you weren't part of GX.Sigma's game, and have no idea what actually happened or what difficulties he faced. Suggesting another poster could just play better isn't helpful. If you wanted to be helpful, perhaps you could have taken the time to list alternatives, such as grappling or saving throws or adjusting the goals of play to remove reliance on combat as a primary resolution path, instead of just implying that GX.Sigma didn't do a good job running their game.
