Self-explanatory. It's nice and all that polearms got a buff, since 1h spear use was nothing short of pathetic, but it seems to have had some undesirable side effects on the 2h side of things. Great weapons using polearm mode are ridiculously fast and spammable now... they really need a speed/damage reduction, and probably the "unbalanced" tag as well. 2h spear use could probably also do with some tweaking, but the great weapons are the main issue here.
