I don't think our points are mutually exclusive at all here. Ideally a group of people queued in solo are going to know what they're doing just as well as a premade group would and thus rendering most of the issue people take with premades moot. That said, a lot of the issues that people seem to have with premades is that they make matches imbalanced by virtue of having better coordination when the reality is that it's an individual player skill/knowledge issue that is easily solved by, you know. Learning to play the game and utilizing the same tools that others are.

Removing the ability to make a full premade party for PvP isn't a solution to a problem that anybody has except for the people that aren't willing to put in the effort to do the same. It's an individual player skill/knowledge issue, not an issue with premades, and I say as much in that post which yours generally seems to agree with.
