Main issues with having mediocre to bad grounded pokes are:
-Lacking or nonexistent boxing game
-Terrible options for dealing with dash>shield mixups without committing to dash grab(and Corrin's grab game sucks, meaning there's no real reason to commit to jump before she does something)
-Trouble dealing with dash grabs without committing to a defensive option like spotdodge, roll or jump
It's not AS big of a deal for
![Cloud :4cloud: :4cloud:](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
because he has a big *** disjoint with half a million safe on shield aerials and the ability to semi-consistently threaten shield breaks.
Every other character with these problems, like

![Zero Suit Zamus :4zss: :4zss:](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
, is bound to suffer as the game ages.
