I don't mind the use of ranks like Captain, Admiral, etc. as level indicators, but IN the game when the characters call you "Admiral" its ridiculous especially given the # of players who are Admiral-level. In our Fleet I am the "Fleet Admiral" and there have been a few times I say to someone "Congratulations, Captain!" (because they command a starship, of course) and they reply "No, it's Admiral!!!" and I role my eyes and try to explain that there is no way the entire Fleet would be composed of Admirals in real life.
Please, Cryptic, remove "Admiral" as something the NPC's say to you... just calling you "Captain" works because you are Captaining a starship regardless of your rank - and just consider Lieutenant/Captain/Admiral, etc. indications of level gameplay-wise, not story-wise.
