One Handed Spear Quicken

[The Roger]

I can understand that Full Adrenaline Rush applies to every weapon you're using, and the normal Adrenaline Rush applies only to Axes/Maces, but Spear Quicken affecting only to two handed spears is weird to me too.
Same stuff for Two Hand Quicken and for one-handed swords the LK has to be linked and use One Hand Quicken to gain aspd with them... If one can swing better a bigger spear/sword, isnt he/she automatically able to do so with a smaller (1handed) spear/sword?

BUT!
Everybody wishes to have more aspd and carry a shield at the same time, so originally this was thought "1hand+shield" or "2hand, no shield but more aspd".
