CC *absolutely* should have a party system. The mode itself is VERY frustrating to play Solo, regardless of Casual or Ranked, because simply people do not listen to Quick Chat, throw themselves at Crystal, and never follow anyone calling shots or anything. FFXIV has a mentality against competitive PvP, but CC intent is to provide a place for Competitive PvP. Therefore, not being able to properly communicate, or play with friends, is a massive detriment.

And if you're that worried about a SoloQ being stomped by a team? That's simple. Make a Queue for teams only, and make a Queue for solo only, in Casuals, at least. That way everything should be equal, right? There's hardly any enjoyment in playing an unbalanced mode, with very bad networking, by yourself and seeing how you're completely unable to turn the tide of the match because one or two selected few that seem to be completely forgetting what the mode is meant for.

That kind of mindset should stick to Frontlines, where they plagued the mode and made it also equally unenjoyable because no one really cares about winning or losing.
