For leveling this is the key path to take.
You can tank, you can DPS and with Int gear +20% from HotW and NI turning Agi into healing, you can heal with ease.

Beyond that, if Mangle is as strong as it was in TBC, you want to bee-line for it, while picking up Savage Fury to buff it. Then, go resto for Furor, Shapeshifter, Naturalist and Omen. At that point you're level 53-54.

Then you have to decide since some gear might be useful to grab and keep for later.

Since dual spec is 1000 gold, if you're feral, grab all of the talents so you can DPS and tank. If you're boomy, be boomy. And if you're resto, I'd strongly advise you dip 30 points into feral and then rest into resto, grabbing Naturalist and Empowered Touch. This means your main heal is Lifebloom and Healing Touch, which is stronger, cheaper and shorter cast. Use rank 3 and 4 cause of the cast time jump between ranks and keep max rank for NT.
You can also do solo content due to 30 points into feral, no problem.

Others posted generalist feral specs and as for PvP, for WPvP, there is the dot boomy/resto spec and feral/resto spec added on top of regular specs.
