This power sometimes causes extremely annoying effect, when it's placed on Cooldown, but doesn't do damage neither moves character. l think reason of that is this string:

If CASTER is positioned 10m to 30m to melee distance of TARGET

Sometimes on client side enemy is still within 30m range, but when command comes to server it's already outside 30m range. This causes power not being executed, but placed on cooldown anyway. Letz compare it with Force Leap/Force Charge Guardian/Jugg power. It doesn't have string

If CASTER is positioned 10m to 30m to melee distance of TARGET

which makes it possible to be casted outside of 30m range, that's why no bug occurs. Solution to resolve this bug is simple: delete string

If CASTER is positioned 10m to 30m to melee distance of TARGET

to blasted hecks.

Also l would like to point, that in tooltip incorrect damage is listed for Jet Charge/Storm, and specifically it's equally 150% damage (0.102-0.162), that Battering Blitz or Battering Ram specialization grants, instead of normal damage. This happens because that value is mentioned earliest within the code, so variable causes exactly it to be shown, but not normal one (0.068-0.108).
