Ugh, yeah, Sersi lost to Sue in a stupid fight of contrition a while back. Sersi couldn't manipulate matter directly through the force field and Sue just kept ramming her down until she was KO'd. Well, it was a dumb issue. Sersi didn't try force like eye blasts or teleportation or slamming on the shield or anything. She just kind of made a dust cloud to reveal the shields and took the beating lol.
In a straight up fight, Sue is outclassed in every sense of the word. Sersi has many options and Sue has no way to down her if she's inclined to defend lol.
