Guys and gals, after maining a retadin since the end of BC, I've decided that a change of class is in order. I've had a desire to get back into healing (I love playing support roles), but I just don't enjoy holy as a paladin.

So, that being said, I'm trying to decide between starting a pandaren monk, mag'har/orc shaman, or troll/Highmountain druid to main for all types of content.

Between those 3 classes, which would people recommend? I won't be doing raiding beyond LFR or mythics because I don't have the time anymore, but everything else is fair game.

Most importantly, which of the threes' healing specs is considered the most fun? Disregard any meta; I'm not after what's best, just at what is generally most pleasing. I have some experience with shaman healing in Cata days, but that's about it.

I'm sure there's a number of guides that could help me choose, but I value the opinions of my fellow Azerothians and would love the input!
