Hello everyone,
im currently searching for an addon that shows me the best target in 1 grp for my PoH. I know that Grid or Elvui have that feature but i wanna play with standard raidframes for some reason ...
You want to play with standard raidframes for what reason? They're shit for this purpose. Every half serious healer uses an addon for raid frames such as Grid, ElvUI, or something else.
Although VuhDo is discontinued, you also got other options available. There's an external ElvUI addon which adds it, and Grid also allows the option as you already stated.
I authored the ElvUI plugin. I've been meaning to make one for the default raid frames since the new API makes it easier in 6.0. Just have a long to do list with other addons.
Until then, you are left with only 3 options. ElvUI+plugin, Grid, or Vuhdo.
