[Known] Knockdown isnt doing correct damage

1. Title: Knockdown isnt doing correct damage
2. Reproduction Rate: 100%
3. Blocker? No
4. Details:

• I am using a staff while fighting elven mages, archers, and fighters in the Rise.
• My damage per hit from Knockdown and Knockback should be similar (See specific numbers below)
• After 264 hits with KNOCKDOWN:
  • My average non crit damage per hit from knockdown is 18.0
  • My average crit damage per hit from knockdown is 36.3
• After 365 hits with KNOCKBACK:
  • My average non crit damage per hit from knockback is 37.8
  • My average crit damage per hit from knockback is 71.3
• These should be in the same range but they aren't even close
• Note: I know knockback hits 3 targets and knockdown only hits 2 targets. The numbers already take that into account. The damage numbers are per hit on a target
• Note: The reason I say knockdown is too low (instead of knockback being too high) is that the relative damage between ground pound and knockback is okay but the relative damage between ground pound and knockdown is off (For comparison, after 226 hits with ground pound avg non crit: 38.0 and avg crit: 81.4
