I don't know the name of it but the mechanics are over powered.
Compared to rune mage or summoner or blade knight and so on, this skill functions as follows:
Stupid high damage with stupid high range and attack speed with no backdraw.
BK : stupid high damage but you HAVE to get up and close in the target's business
RM : stupid high damage but the attack speed is super slow & the skill casts with a delay, so you have to aim ahead of your target
Sum : high damage AOE
And so on...case in point: the mechanics of the DL Ruud skill are op, and they need a balancing , as all the other ruud skills have pros and cons, just like you wouldnt use the BK ruud skill for mass clear, but rageful blow or destruction.
Players, please comment your opinion on this, and admin, i hope you understand this perspective and rethink the skill.
