Demon Form Suggestions

The only thing I don't like about Demon Form is that it starts from 0 stacks whenever you pop it or zone. With very few investment you can reach 2-300 stacks easily but you will eventually drop the form and go from 5000% increased spell damage to 0% because you have none on the tree, so you have to wait a minute in a corner to build up stacks to be able to do some damage again. So mapping goes like zone in, wait for 30-40 seconds because without 30-40 stacks you're a wet noodle, jump in, go on a rampage for 3 minutes, drop the form, wait a minute again, rinse and repeat. It kinda sucks.

It would be much smoother if Demon Form regained 50% of the stacks it had when the form ended last time. So if you drop the form at 250 stacks, you start at 125 when you pop it again. It could even be an ascendancy passive, you can't really spend your ascendancy points anywhere on a low life Demon Form build anyway.
