Even if team building, groups and units is useful to the game, MWO has been shockingly bad about supporting it. It took them forever to provide LFG and so much of things needed to support it are not in the client and circling back to solo players are the majority of the player base, unless its within client there no way for most to easily or possibly find. People shouldn't need to go to discord or see whose streaming on twitch to group up on demand, it should be in client.
Which I guess leads back to what this experiment is supposedly about if we don't buy into the Soup Queue Mk II conspiracy thoughts, event queue. I am very worried that the experience shown this weekend means that like Faction Play and Solaris that solo players will try the first few events and nope out as organised group farm until only the groups are left and who will complain about wait times because with declining player base there are not enough groups to get matches quickly even on a specific event weekend.
