Thread: [Help] Set 70

I wonder what the best set of rare 70 to be used by warrior, I was told that the comet is the best because it has an effect that helps kill faster, and the freeze would not be better because it freezes the opponent?
And one more doubt, the effect of freezing on several targets picks? example, use a skill in area, the effect has a chance to achieve everyone within that area?
Thx
