4th job wildhunter builds?

I don't know, before big bang people on southperry told me skills with cooldowns aren't dispellable, like concetrate.

I find it weird how concentrate can't be dispellable while our's is =/ Even though we copied it almost exactly! (ok maybe not but still)

I haven't really checked recently, since I was afraid to use concentrate during chaos zakum but can anyone verify that concentrate doesn't get dispelled?
