I have more trouble with agility polearm S-keyers than any other class, especially when they are sideswinging with a War Spear or similar. Those damn spear sideswings go right around shield blocks and hit way faster than they should. This was the one scenario where hybrid throwing was awesome, but I don't have throwing anymore so I usually chase them and take a stab to the face with full speed bonus while they outreach my 1h stab (even though I theoretically have 10+cm more max stab reach than them, it's not "useful" reach because it takes forever to extend that far and glances anyway).
If I had more discipline, I'd pretend to disconnect every time they started S-keying. That would lure them back.
