Well actaully the blue stance upper cut (lunge) has some good points and seems fairly balanced. In fact it seems so balanced I'm sure it will get jacked up in the next patch for sure.
It kills in 3 consecutive lunges (fairly balanced power)
It blocks most red stance swings.
It can sometimes block a blue backstab.
I have blocked the DFA with it a couple times.
It is a great counter to a dfa after landing.
It is a great combo to include with the backflip if someone charges.
It can close the distance to a dfa so you can avoid getting squashed.
Its above average power when compared to the normal swing is balanced perfectly with just the right amount of animation delay.
