The increased use of motions to strike arguably is in lock-step with Wal-Mart Stores Inc. v. Dukes, 131 S. Ct. 2541, 2550 (2011) and Comcast Corp. v. Behrend, 133 S. Ct. 1426, 1432 (2013), which remind us that class actions are "an exception to the usual rule that litigation is conducted by and on behalf of the individual named parties only."
