This simple Addon checks your Friendly target and keep it up.
As soon as you lose your F-target, it sets your char as F-Target.

I play a Healer (AM), losing my F-Target time to time was very frustrating because some Spells need a F-Target to be present.

This addon check if you currently have a F-target selected, if not it make a simple selftargeting. So in hectic battles you are at least sure that you are the default target.

That's it.

Slash commands
There is exactly one. /selftarget which toggle the Addon on/off

Requirements
This Addon needs two librarys. The first is LibSlash and the second one is LibTimer you can download both in the Warhammer Addons on Curseforge.
