If someone spams, hold, if someone feintspams, make a chamberattempt on his first feint, if he releases, you chamber, if he feints, you get a free hit, if he hold, you're likely gonna get fucked.
Don't hold against spammers that's how you give them free hits, spam relies on your opponent making timing/positioning/swing direction "mistakes" holding an attack or delaying your attack turn against some one who's letting off attacks one after the other will end badly.
Agreed with the second part though.
Thats not true . On failing to chamber a feint you will still get fucked pretty often . At least with DGS against a wide variety of faster weapons - 1h,fast swords etc. - but often enough against other long weaps - other GSs, Axes, spears etc. Best tactic agains spam in my expereance is simply out-time by finding a window in the spam pattern. If you miss the window , you can still emergency-block, thats pretty safe imo.
Biggest problem was always delayed attacks , because they make it hard to get the right timing ...
This is true, using slower weapons you have to realize what you can and cannot chamber. With slower 2h I will never try to chamber an overhead especially from faster weapons because of how easy it is to feint out of the over head and into a side swing before my chambered overhead would have time to hit.
Delayed attacks or holds fail to spam/educated swinging easily, they're giving up precious moments of their attack time and it takes up moments of yours if you let them do it. Holding/delaying attacks only works if the person is following the "I attack you block, you attack I block" game.
