The problem with her not being able to jump is the messy collision on the terrain. Just like it messes with Brainz combos, it also messes with her charged movement. There are plenty of spots where you will get stuck on some arbitrary obstacle that she would simply fly over if she would actually glide like the animation depicts. But since she is just walking on the floor like every other character, inclusive the burrow animation from the Chomper, the forced walk while charged removes even more of her mobility due to the lazy job on collision in this game.
It's completely reasonable that she is slower, but to overcome the uneven terrain Popcap either has to redo the entire walking physics or give everyone a chance to adapt. In this case allow her to jump.
She already got buffed a bit because her early charged state was way too punishing. But now we still have this problem with a gliding character that cannot glide over tiny elevations.
I haven't encountered the terrain collisions which you describe with Rose but that's probably because I don't try to carry a charged shot for a very long distance- I am however very familiar with it due to the heavy interference the terrain inflicts on the Unicorn Chompers Rainbow Warp ability.
I gotta agree with OP here. I don't use Rose much, but not being able to jump for charged shots is a huge hindrance. Sometimes the target is behind a fence or wall that you could normally hit if you could jump, forcing you to give up ground to get in position for a clear shot.
I think they should be able to jump, but then you have to cut some damage, or make the charged attack, charge itself slower to balance that, i think they're both fine, but nevermind for a good healthier change
