Some people complain about how (especially with dual wield and sometimes 2handed) how it can be repetitive. Even with all the perks in 2handed, you are limited to:

Regular Attack
Power Attack
Sprinting Power Attack (Great Crit Charge)
Sideways Power Attack (Sweep)
Backwards Power Attack (Warmaster)

plus you can block and bash with your weapon, but thats it.

A possible idea would be to have more power attacks, like maybe an 2hand power attack that has a chance for knockdown, or another with a stun, or maybe a special power attack for someone who has just a 1hand sword in one hand and an empty left hand where you sort of dash backward, then lunge forward like a fencer. Maybe a special short block, then counterattack for dual wielders?

How you would do it is have seperate perks for each attack, and then the player would have to assign which power attacks they want for each direction (Sprint, Forward, Side, Back) so that players could mix and match their power attacks and create a somewhat unique style for each character they make.
