Nerf the Symmetra wall climbing technique

Symmetra can climb wherever she wants in the game Overwatch due to a glitch allowing her to "step" on previously placed sentry turrets, thus allowing her to go to previously inaccessible areas. i'm concerned because this defeats the purpose of Symmetra being a low mobility character. I would like for Blizzard to change the entity of the turrets to disable Symmetra from climbing on top of them.
