How it works:

Creates or updates the AutoInnervate macro so that your innervate always goes to your healer without needing to target them in a dungeon group.
When you are not in a party, it transforms into a mouseover/target innervate macro.
You can type /setinnervate while in a raid and the macro will update to your current target. Type the command again without a target to reset it to mouseover.
Auto Innervate does nothing if you're not a druid.

How to use:

Install addon
Find the AutoInnervate macro in your character specific macro page.
Place the AutoInnervate macro on your bars

Changelog:

1.1 Added fallback to mouseover macro instead of keeping the player number macro.

1.2 Made the macro character specific and added a druid check.

1.3 Added /setinnervate command to set the macro to your current target while in a raid. It also prints what your macro currently does when there is a ready check.

1.4 Fixed ready check print in party

1.5 Don't worry about it

1.6 Fixed cross-faction macro not updating, and the macro sometimes being created in general macros instead of character specific macro. Make sure you delete the general macro if you have one so that it works properly.

Inspired by the Auto Potion addon by ollidiemaus. Check it out if you want a one button macro or keybind that cycles through your healthstones, healing potion, and self-healing spells.
