Guide for Returning Player?

I was playing WoW nonstop from 2010 - 2013 then decided to quit (During Cata then MoP expansions). It’s been almost 6 years and finally I’m back just to see my lovely main and alts.

I never raids, my main invested time is to gather mounts/pets, doing BGs, Arenas, collecting items for transmorg by doing low level dungeons and raids… And I enjoyed that greatly (during my college time).

Now back to the game in 2019, everything is so new to me and I’m having a bit of difficulty to get back to all the mechanics, so is there any good guide and instruction videos for long time returning player like me? Perhaps leveling a fresh character is where I should start?

Thank you so much for any feedback.

Both icy-veins.com and wowhead.com have decent class/spec guides. They tend to be oriented towards level 120 but will give you a good idea of talent choices, rotations, etc…

Playstyles for many specs has changed over the years. I would suggest playing around with a couple of different classes while getting a handle on your old toons.
