The feature this game needs the most: Training Mode!

A mode where you could pick your character and set up the dummy opponent to do whatever, just like any fighting game. Just to have the option of choosing how the opponent will react; autoblock to see if you're actually combining, set to do specific attacks so you practice parrying those unblockables, an auto tech on the guard breaks to see if you're getting the guaranteed break after the parry. The ability to record a set of actions for the dummy to use against you would be an amazing feature. You could practice against a Warden doing the light into shoulder and figure out how best to dodge and punish it.

Realistically I don't see it happening but if this game really kicks off people will want to know the best options at all times, the best way to do that is through training mode.
