I personally think turn based combat is fine enough on its own. Not something that'll sway my opinion of a game that much.
I know of maybe 3 titles that I've played, all of which are part of the same MMO universe, that do it, but I love the turn based combat where you have a certain number of movements you can do, followed by a certain number of actions. Makes the strategy side of things much more enjoyable rather than just having to hope the enemy doesn't use a specific action.
Though, I mostly grew up with more free action based RPGs and such, so I really don't mind them as well. Makes certain titles, like New Vegas or Borderlands, much more enjoyable.
As for leaving it behind or not, totally up to the devs, for the most part.
I personally would love to, if I ever had the coding skill and drive, make a game featuring the aforementioned turn based combat system I love.
