Both casting time and recharge time changes during Momentum. Proc chances will be lower then.
The charts list them as the same chances as non-momentum.
Axe Cyclone and Fire Sword Circle appear to have forgotten their AoE nature in the proc chance. Titan Weapon during Momentum probably needs its own chart since they have different animations and recharges.
You should be factoring in proc chance some how.
For example, Beheader only has a 28% chance to proc, while Swoop has a 74%.
Not to mention Beheader is garbage and should never be used, while Swoop is your best attack.
Can anyone explain to me exactly how procs have been impacted on Radiation Therapy and Ground Zero?
It feels like chasing a moving target trying to figure it out.
