They lost 1 speed while all the other good swords gained 1 speed. 2 speed is quite a bit. They used to be the best weapons for dueling, good for siege and average for battle. Atm they are bad in all situations compared to SoW except for when fighting in very tight places.
But to be fair, SoW is OP compared to most 2h swords that can stab. Only swords that can match it is the Claymore and the GS, but even those falls a bit too short.
