How exactly does the Centurion parry counter work? So many times he'd do it when all I wanted to do was grab someone and splat them against the wall, while other times I'd try to counter but he wouldn't do it and I'd miss an opportunity to punish my opponent. (I'm JUST starting to get my hands in this character; rep 32 Warden and rep 10 Highlander here)
Help please, thanks.
