If this was already asked, I didn't see it, so if this is a duplicate, then sorry.
How much better does a ranger get if given the ability to fly? Like, for monks or barbarians usually not much changes, because you need to be in melee range of the opponent to hit them anyways, but with things like wizards flight allows a retreat to keep enemies away from you as you cast whatever spells you want from a distance.
I'm wondering how much a ranger would benefit from flight, on a scale of monk-wizard, or 1-10 if that's easier to understand. Like, if I want to play a ranger, am I better off doing so with a flying race?
