[Union] [Adventurer] Thief

It easy enough to know the precise for rush a dual blade can rush mobs all the time perfectly fine. Don't see why a shadower can't either. Only time you lose mob control would be in lhc where as when other classes hit mobs you can't rush them. Foreign spell is used as a finisher. If there is no floor underneath you most likely won't move at all. You would be worst at the arms in zak. Which doesn't matter as we have the potential system your range should be enough to to kill arms relatively fast with boomerang step alone. Edge carnival was meant or more to replace assassinate. Once again nexon has no logic. The fact that shadowers are not based around dark sight doesn't make sense to me. They could easily reward using dark sight as the base of the class. This is just first test patch things will be change most likely. All they really did was it up.

With the introduction of Party Play and Monster Park we almost never train alone, therefore losing mob control would happen every time you are training with other people.
How is a Rush Skill a finisher? Even if it was a finisher, because of B-Step's delay, what we need to put in-between B-Steps is not a finisher but another mob skill, just how BoT was.
And the Arms at Zak does matter, because spamming B-Step has never been a proper way of either training or bossing. The whole "Shadower-way", if you will, is based on having a Skill follow B-Step. Using multiple Skills while both training and bossing is what I like about Shadowers so much. I don't spam one Skill.
In my opinion Edge Carnival it's not to replace Assassinate but to replace Savage Blow. I still have high hopes for Assassinate and the Assassinate point system. As you said this is just the first test patch and they have time to fix some stuff. And hopefully they will.
