Against Hilde, who has an extremely long spear that she likes to stab you with from across the level, I've been having trouble getting in close enough to deal damage.
Against many players, 236A+B is a solid choice because it is a long-ranged low, but skilled players can block this on reaction and punish you pretty hard for it, not to mention that Hilde keeps you so far away that even this probably would come short anyway.
The crouching 3[A+B] is easily sidestepped, and leaves you just as open.
Are all Voldo's long-range moves like this unsafe? I know throwing out random moves in general is not a good practice, but is there some string of attacks that will safely close distance? Does Voldo have a move with a secondary Guard Impact effect that will counter Hilde's long-range thrusts?
