I agree, that's why I said earlier that shield disables should be much longer than 5 seconds. Something that I like to do when disabling a shield is pressing "wasd" (in that order) to get something similar to a circle strafe and spam click then. If done at a proper position it'll disable their shield and u will be out of the distance to where they can hit you which can deter their crit chain.
Someone gave the suggestion of getting a certain amount of fully charged hits would disable a shield too which isn't entirely a bad idea either.
Also, I'd like to add for all the people that say shield is a skillless item or whatever, how come if a shield is given to a random player, they don't perform as well as say HyperTotodile? Also, if shield is such an OP item shouldn't top damage and kills be dominated by shield pvpers?
