I don't like this "neutral attacks do way too much, but resisted attacks are insignificant" thing. There is a whole continuum of damage that can be done to Tyranitar. You can't just assert that there is some sort of enormous gap in it. The physical choice pokemon I'm referring to are largely scarfers, e.g ScarfMence, Scarf Landorus locked into Stone Edge rather than Banders. Strangely enough a neutral attack from a scarfer will do damage somewhere in between that of a Choice bander using a neutral and a resisted move.

Obviously, if the opponent is locked into a neutral move, using Pursuit may be a mistake, but the ability to take the hit and KO back is invaluable. You might take a resisted move on the switch-in before using Pursuit, either.

Plus, one thing I forgot: Tyranitar often takes U-turns from Special attackers like Celebi. With 11% less physical bulk these are really going to do a significant amount more.
