Havent done any raids or ToO despite being a Day 1 player as just dont have time with work and life stuff to go through LFG, figure out a decent group, wait for replies, coordinate when to do it etc. I understand reasons people dont want matchmaking or feel it wont work but if it's optional then whats the harm? people know what they're getting into and could be pretty fun (in a disasterous kinda way!!) and is a quick and easy way to make raids available for all
