Better give them updated honest feedback with the good and bad aspects of it and let them decide.
Not every player looks for the same to begin with, some people won't mind certain aspects, so it's better to let each try for themselves.
I believe if by the time you get a content it's outdated playing actively, it's not really pay2advance or fast any longer, it's a non strict form pf p2w, but this is just my humble opinion and subject to discussion. Then again the BiS is not needed to enjoy and access every game content so there's that too.
