OM works with both subclasses. Other than not having the nova to help with super regen, it is still very fast with Juju. I've used it with Sun Singer and I can actually use Radiance without having to wait an entire event for an emergency and possibly never use it. Last week's NF I used it a lot and because we know what we're doing, we never had to use my self res. I was able to contribute to the team and not just sit back and wait for something bad to happen. Juju is a good gun if you know how to use it, especially if Juggler mod is on. Sorry to blast holes in your theory, but there are other ways to play a Warlock if you take the time to learn how.
