WoTLK fan 1st time experiencing the expansion(post Retail)

Hey!
I have been the biggest WoW fan ever since I was a kid. My first ever game as a kid was playing WoW, while sitting on my grandpas lap and that was right after Burning Crusade launched. I never really picked it back up until 2015ish or later because Legion was just ending and BFA was on the horizon. I am really excited to be able to experience WoTLK in the classic form, while blasting through the dungeons as your DK tank. I would be interested in joining an active guild, after I have had some time to get to understand how Warmane works and runs. I usually am a tmog/rare collector so that still might be my priority hahaha.
