Infernalist help with build

I am looking for a new end game build, utilizing demonflame without demonform, for comet or firestorm spam that is not centered around a flask spamming build.

Any suggestion to a build that utilizes Barrier invocation, cast on freeze/shock or other reactive skills for constant mass aoe clearing, that is not centered around flasks?

been using a minion build up to this point, but grown increasingly frustrated by minions getting stuck and dying randomly with full health.

So use detonate dead if your minion die.

To be honnest, demonflame just sucks right now and its really bad. Firestorm too. Comet is a good one with cast on freeze/shock but its already a build existing.

If after 1 month, some really good builders playing 16h a day this game, we have no build with such skills, its for a reason I guess !!!
