From personal experience if your DD is not challenging herself against not just better opponents but better teammates she will not develop. My DD had a weird to bad 12u experience. Moved up to 14u got hurt and quit softball for awhile. The next fall wants to play again gets on a 14u team with some good players but not pitchers. Played against A/B teams that fall and basically got crushed. That spring they are entered in to just C tournaments. Let me tell my daughter that summer was like the combination of Babe Ruth, Ted Williams and Yadier Molina. She it the heck out of the ball. Was selected to play in a C level MO/Kan Allstar game was pretty clearly the best hitter there. She is feeling great then high school tryouts started. Before they started she was thinking she would be a shoo in for varsity. She barely made JV and took half the season to start hitting getting used to the pitching. This past fall playing JV so had a great season hitting. But the goal is varsity, so we have moved up in talent for this spring in levels of both coemption and teammates. So varsity pitching is not a shock to her.
Your DD's have to keep being challenged if the goal is to keep advancing. Sure playing is part of that, but so is playing tough coemption and being pushed by your coaches and teammates.
