Pretty much I enjoy my experience as a shuffle player better than a 3’s player overall. If in 3’s you could find a team anytime you logged on, at the exact skill level you are at and play against a diverse range of comps, while also playing any spec you want. the 3’s experience would be better. But since that almost never happens unless you are a decade long player with plenty of bnets, then the 3’s experience is not as good for the majority of players
