Post-patch: Variable, 1-5 seconds
Reason I think it should be changed: Damage is too low and it's only really viable in PvM.
I think you should use all the spheres (the level depends% dmg a sphere).
lvl5 with 5s: 5k dmg
lvl5 with 10s: 10k dmg
lvl5 with 15s: 15k dmg
lvl1 with 15s: 3k
lvl1 with 1s: 0.2k
lvl5 with 1s: 1k
work like RB..
without LR sura weak in PvM, and not have any usable skills... (SB low, RB cd10 sec, TC use HP/SP+Low splash, GoH pvp and single target)
Or mb lower CD on RB.. 2-3 sec.
They also should restore the effect of DEX on the skill.
