Pierce is only slightly better than blunt (maybe even worse against high armor actually since the soak modifier change), 1h hammers and maces are barely slower than picks, slightly longer, heavier (no block stun), even the cheapest 1h maces have very good stats and most importantly they all got knockdown.
Imo 1h hammers are superior to picks.
It's true sword stabs could use a buff though, especially those that do less than 20 damage and glance on everything. It's almost better to get a no-stab weapon in that case.
