Has anyone been able to make work, especially in higher difficulties, the non-standard primary skills. By standard I mean things that seem to be posted quite often (spray/devouring/LB)

I'm just curious if anyone runs decent builds, with primaries that we don't often see posted (I dunno, e.g. imminent doom, shock collar, crazy stuff).
Always interested in people's creativity

PS also appreciate this isn't even a QQ or hate thread
That is all.
