Calling them raids is not convoluted. Refusing to call them raids, is equivalent to making a platformer and insisting that people call your core mechanic "leaping" not "jumping" it's different because you press the A button instead of the B button!
See how ludicrous that sounds?
Having a broad category is not useless. Raids encompass the higher level categories you seem to have a major hard-on for (Salvage, Limbus, 10-Man, 25-Man, etc. All of these are sub-categories of raids for specific games.) Think about it in terms of animal kingdoms, genus, phylum, etc. A cape lobster is Arthropoda Crustacea Malacostraca Decapoda Nephropidae. Go tell a biologist its useless to classify a Lobster as an Arthropod, because insects also fall into that Phylum.
Having a broad, widely accepted term for a specific type of thing isn't a new idea, nor is it a bad one, nor does it detract from your specific terminology. How can you not wrap your head around this? Classifying things is a natural human tendency, and it's useful to help other people understand.
If I tell you an animal is an arthropod, you can make some assumptions about it. You don't need to assume that because I said Arthropod, I meant a Cape Lobster.
In WoW raid means one thing, and in Lineage, raid means another thing, and in Everquest, raid means another thing, and yet they share some commonality.
If the Crystal Tower is a multi-party, loot driven event that requires a pre-formed party (i.e. is not a public event) IT'S A RAID. And you can make a very small number of appropriate assumptions about it, all of which are things the development team have stated. (It's end game alliance based content.)
