Looking to return to retail

I played classic for a while but I stopped a couple of months ago.

I am looking to come back to retail and I was wondering if there is still a good community retail? also what is the talk around Shadowlands? I dont really get into end game raiding, kinda like to run dungeons and do some pvp. looking for some class suggestions say 1 plate class one none plate for dps and one caster for either heal or dps.
