One of the biggest annoyances I have with many of the posts upset with ArenaNet, is that they do not even know what the word LIE means.
Even IF way back when, they said something would work one way and now it doesn’t, it does NOT mean you were lied to.
Lie:
a false statement made with deliberate intent to deceive; an intentional untruth; a falsehood.
So unless you really believe when they put out a given statement, it was their intent at that time to be untruthful, it is not a lie.
