Well the purpose of GWF was to mitigate misses.
With Next's squishy PCs and only having 1 attack per action, they had to give a melee GW warrior something to contribute if he misses. Because it is pretty bad if your nondefensive melee guy deals no damage for 3 or more turns as he is probably taking damage or dying in the mean time.
Maybe Damage on a miss is not the best way to mitigate a GW warrior's miss streak. Maybe a bonus attack if you miss could be better but the design team kinda hate bonus attacks.
