Agreed, I never leave home without my trusty Zwei. It's so satisfying seeing someone waving a buckler around wildly, only to crush them in 2 swings. But it's also satisfying to parry that guy who's spamming Katana sprint attacks, or running around in circles like a twat thinking he's being 'unpredictable'. Parrying is just the icing on the cake; it isn't necessary, but it gives PvP a better flavour.
