Autoattacks carry counterplay due to forcing interaction at risky ranges. This would be particularly true of Cassiopeia, who isn't particularly resilient or mobile. She would also still be required to land her skills, as her attack speed wouldn't be anywhere near sufficient to ensure good damage output on basic attacks alone. If anything, she'd carry a lot more counterplay than her current iteration, whose damage is primarily based on a spammable point-and-click nuke.
