Actually, "players online" is perfectly correct. I get what you mean, but what you want to say is "characters in-game" in that distinction. A logged account still means a player online, although it might not mean a character in-game. Even then, that might have applied when Lordaeron had a queue, which doesn't happens anymore, so the need to "save spots" doesn't exists - and even when they did (or still does in Icecrown), according to Proterean the number of accounts doing that is tiny, enough to not make it worth it working on kick timers. Considering how people say Lordaeron is "dying" or even already "dead" with peaks of 10k players, I'm inclined to believe him instead of the players who claim there are thousands doing it.
