I noticed I get very confused by unclarity in any match. When I play with a significantly more aggressive partner, roles are clear. When I play with a significantly defensive player, same thing.
I play at my worst when I am with an equal partner, because we lose a lot of time waiting, watching, thinking what might happen.
It really helps to have role clarity. One person should act as attacker, taking control over the center of the court, taking all the attacking opportunities. The other is supportive. If both players are more or less equal, this doesn't happen naturally and you need to make an effort to establish this role clarity.
I totally agree with you, I think we have this issue while playing
