Sonic Resonance
Sonic Siphon: Change from single target to target AOE, 8-foot radius.
Sonic Repulsion: Reduce endurance cost by half, from 1.04/sec to 0.52/sec, remove the -2.5 endurance from each target knocked back. Change knockback to knockdown.
Clarity: Add small heal, same level as O2 boost. Increase endurance cost to compensate. Sonic dispersion makes this power somewhat unnecessary in most situations - this will give it some use.
Liquefy: Reduce recharge time from 300 seconds to 120 seconds (4x power duration).
Trick Arrow
Increase all non-defender debuff values to current defender levels (masterminds might not go to defender levels, but they should still be increased from what they have now), increase defender debuffs by ~20% or so.
Poison Gas Arrow: Change from 66% chance of mag 2 sleep to 100% chance of mag 2 sleep. Increase -damage debuff duration from 20 to 30 seconds. Keep the non-stacking component.
Oil Slick Arrow: Just fix this buggy power. Please.
Thats all I got for now.
