I'm fairly certain most of those terms have been applied to MMOs since their inception and are therefore universally recognized by the MMORPG playing community. I understand that in an effort to immerse players in the game world Bioware decided to rename dungeons and raids, flash points and operations but that doesn't change what they are.
In short if it walks like a duck and quacks like a duck, then it's a duck. Or in this case they are dungeons, raids, and pets (specifically combat pets, with the exception of the annoying ship steward).
