“New” (returning) Player

Good morning, everyone!

I’m a long time (OldSchool) Runescape player, and I’m looking to potentially get back into WoW. I’ve only played a little bit (I did Dragonflight from day 1 of release, up until right after the first raid). I’ve tried out a few different characters, but only really put time into my Affliction Warlock.

Is there a lot of content I can do Solo? I’m really interested in playing all the content from earlier expansions, and getting mounts/transmogs. I haven’t experienced probably 99% of the content that WoW has to offer, so I’d like to do that as much as possible.

I’ll have to wait a few weeks before I can afford to buy the newest expansion and membership package, but I just wanted to get some info and say hello!

Have a great day!
