Hello!

As other people said earlier, having a team of 3 from your server or merged server will queue you much faster and will able you to find matches right away. On the other hand, if you're only solo in a team or you only have 2 members in a team, the system will try to find another individual who queues solo and team up with you. As for your statement of queueing alone and getting paired up with other people, yes, it is possible before but now, it is not possible anymore. Going inside and queueing alone will put you on hold while the system finds you other players, within your server or merged server, it is not the same anymore like the first few 3v3 Arenas in the past. Thank you.
