As a casual player who played all healer classes up until around 3.4 was released (and then took a long break from the game) I'm quite saddened to see the current state of the healer classes upon my return a few months back (and don't get me started on Summoner!).
It feels like they've been really dumbed-down/simplified and lost what made them unique and fun to play, I almost wept when I realised that Eos and Selene had no differences aside from their looks, nearly choked when I saw what had happened to the AST card deck, and still wondering when did White Mage stop borrowing from nature and go full on light-mage (is it some sort of remnant to what happens in ShB?).
You've all pretty much covered it already for suggestions so won't go repeating it but SE for the love of all things healer, please do something about them!
