CVar spreadnameplates

Controls whether nameplates shall spread out, or are allowed to overlap (like the old nameplateAllowOverlap functionality).

• 1 :Enabled by default.

• 1 :Nameplates may not overlap, and will be constantly shuffled around to fit on the screen while remaining as close as possible to their units.
• 0 :Nameplates may overlap, and will stay more or less directly above the units they represent.

In-game, type the following /console spreadnameplates value

Alternatively, you can exit wow, open the Config-cache.wtf file, and add the following line: SET spreadnameplates value
