Finally someone posted about this! Yeah! it's so OP! I mean, it's like instant death to anyone targeted. The only way I can think of countering this is by using a Advanced Potion of Passion (or something alike). Unless if you really have a very large amount of HP like Templars, you'll die in 2-4 hits. I mean, it's a sure hit! >_<
I already have roughly 100k HP and this hits me like 50k per hit, and they hit so fast. Even if try to move, the skill itself has 12m dash like Notrom said. If you've been nerfing wind walkers because of small issues, then this should be nerfed too!
