Thread explaining this on MMO-Champion:
AoEonRelease makes your ground targeted AoE spells show the ground targeting circle when the key is pressed down, then cast the spell when the key is released.
This project was originally a plugin for ElvUI, but the second version should work with most action bar AddOns. It has been tested quickly with default UI, ElvUI, Dominos and Bartender.
This is a very experimental project, and will not be actively updated. I will occasionally take a look at any easily solvable issues.
Known issues:
- The AddOn uses a manually written list of ground targeted spells, which is still incomplete. You can add missing spellIDs manually to the .lua file. Please feel free to report all the missing spells for your class.
- This doesn't work for abilities bound to mouse buttons. I'm almost positive this is an issue that cannot be solved through changes to the AddOn. This issue can be avoided by rebinding your mouse buttons into other keys through 3rd party software such as AutoHotKey or the software that comes with some gaming mice.
- In the restricted environment, where this AddOn mostly operates, there's no way to know whether the ability you want to use is on CD or if you have enough resources to cast it, which means that the ability will be cast when you release the key even if the ability was on CD when you pressed down the key. In this situation you naturally will not see a targeting circle. This issue could potentially be fixed, if there was a way to toggle the ground targeting circle by using the ability again.
- Macroed abilities are not detected.
- Forces abilities to register on key down, disabling RegisterForClicks for altered buttons
- Bars 2 and 7-10 don't work with Dominos.
Possible issues:
- Hasn't been tested with all spells, for example Angelic Feather
- Hasn't been tested in different situations that change your action bars
