That was already the case way before we had solo shuffle, it is one of the reasons solo shuffle got released. Because arena with LFG was a nightmare. 60 min looking/searching for partner… get into game win one game, lose one game. partner rage quits without saying anything. Back to waiting/searching in LFG again.
And on op of that, you couldn’t do anything else while sitting in LFG, not skirmish, no BG, nothing. And I am sure that this is still the case right now.
I love playing arena with a real team, I did it for years. Nobody I know plays anymore. And before people come here and say something stupid like: “make new friends”. GTFO here dude. in Shadowlands I added like 40-50 people on my Battle Net and with not a single one did I play ever again because… either they do not log in ever again for weeks. Or they log in and still have the same gear and are very behind.
Or they stopped playing their class and are on another toon, of course with low gear again and the only reason they would play with you again is to gear and cap their twink and then never play that toon again, too.
Or they straight out just never play at the same time you could play at, therefore no chance to spam arena games. Or they just don’t answer ever again on whispers. And I am telling you, most of them are scared to play properly arena, anxiety plays a big role in competetive games, many people have that issue. Most people rather play a Twink and gear that one up then move on to another character again instead of doing try hard rating gain in arena.
Players that have teams or partners are 99% those who met 10-15 years ago and are still playing and they never needed to “make new friends”. It was the same for me, for years. It is easy to tell others “just make friends” in a game that has less and less players year to year and getting more toxic on top of that.
AND on top of that, you for sure do not wanna have to train somebody, even if that person is nice and cool and can and wants to play. If you have some exp on higher ratings it is not really fun in the long run to play with people that have absolutly no exp in a 18y old game. It just takes way to long to get on a decent level.
