What about sandburst, windblast, frozen blast, life drain and barrier spikes? that is not utility?
I think it's more debuff then utility. But, yeah. You can say that it's utility because some skill cause very low-damage to be called attack skill lol.
But from my perspective, I think those skill are more Crowd Control then utility (atleast what I used it for). Sand Burst used for dropping aggro in tight situation, I don't think anyone would just used Sand Burst when you fight only 1 monster... Wind Blast is also like Sand Burst but not dropping aggro. I highly doubt someone will used it for Crowd Control, also have less utility then Sand Burst. Frozen Blast is very useful in Crowd Control debuff skill. Life Drain also have high utility but I can't say for sure since it have high damage too... Barrier Spikes ... Well, I really didn't use it in SM very much. I think it's only useful in some SM only...
But I admitted I forgot about those skill completely XD. If you want me to rate the utility again, I gonna say 2/5. But If there're Debuff score I gonna throw it at 4/5 XD.
