I'd be fine with Parry staying around or being buffed if (the revised) Parry:

1) didn't inevitably weigh higher for a short time during early progression, and continue to fall thereafter
2) wasn't useless when not actually taking physical hits (OT/magic)
3) was more controllable / reliable
4) interacted with the other secondary stats
5) won't on average outweigh those other secondary stat choices
