I love the new Arcing Slice (Greatsword Burst) 
I have a few ideas for improve GS autoattack and 100b
__________________________________________________________________
Greatsword swing #1a
250→280
Vulnerability 1 / 8s
Greatsword slice #1b
250→280
Vulnerability 1 / 8s
Brutal strike #1c
322→300
Cripple 1s
100b #2
Damage 4X 1500 → 8X 1624
Final strike 406
castime 3.5 → 2.0
cooldown 10 → 12
the idea is to drastically reduce the damage of 100b but make it easy to land and balance the damage nerf with a improve of autoattack
what do you think?
