RE4 has the same spinning. You can't strafe, hence tank controls. You can spin and go back or forward. OTS camera allows precise aim, but it's beside the point.
Some "problematic" people might find a bit of fan service problematic, but outside of that I don't see anything wrong with Ashley. As the most desperate move to add something to her, I'd probably give her some heroic moment in final parts of the game. Something in fashion of Helen Tasker in True Lies dropping Mac 10 and shooting bad guys. Something that fits her clumsiness and innocence, yet saves the day. It will also fit the tone of the game, which is intentionally packed with Hollywood action blockbuster tropes and doesn't take itself too seriously.
