This isn't just a problem of L7 elite destroyers vs. all other naval units. All of the elite units take absolute precedence in formation naming conventions over all non-elite units, so you can wind up with some very misleading stack names; for example, the "75th Militia Division," composed of 25 L4 medium tank brigades and one L7 militia regiment. That's goofy and seriously misleading. The formation naming conventions should be restored to their usual order of unit precedence, and the special naming precedence for elite units eliminated.
Also, while the Bytro Labs brain trust is fixing this, can you please flip the precedence so that aircraft carriers have formation naming priority over battleships? Not only would that be correct in any major navy since WW2, it would also eliminate the strange graphic anomaly of having carrier aircraft sitting on a battleship icon.
(and cruisers too)
