While I agree with the point that this can be fixed without majorly nerfing the entire class... I don't see "half of all warlocks" as a tiny fraction. Everyone who isn't a blastlock is a Bladelock, and we've proven fairly strongly that the issue isn't ONLY spirit shroud. Heck, my analysis didn't use Spirit Shroud even once, and I outdamage a PAM+GWM+Charger Fighter build. And even after corrections, it is far too close for a build that utilizes no damage increasing feats and is only using half their invocations. It is half of a warlock able to compete with a fighter devoted entirely to one build and strategy. That's not good.
