EH - DemoLock
This is an addon designed to work in combination with EventHorizon
I've been using EventHorizon for quite a while, it's a fantastic add-on that shows me what I need to know in a compact way. It also does great in effectively letting me look into the future a little bit clearer than most add-ons do- to pre-plan my moves better.
For Demonology Warlocks however, some vital information is missing from EventHorizon. Notably, EventHorizon doesn't show Molten Core and Decimation. Now, it's not impossible to add buff bars for those 2, and it would work... But with 6 active bars to look at already (trinket bars excluded) and a UI that doesn't really have the extra space, that's not really something I want to be doing. Instead I chose to write an add-on that would simply draw a molten core / decimation icon on top of the Shadow Bolt Icon when either of those 2 buffs is active. The icon will display the number of stacks for molten core, or the time remaining for Decimation.
It's very basic, and far from perfect- and I actually will continue to also use power auras along-side EventHorizon. But it's still nice and sort of useful (especially without Power Auras or alike).
