I don't get your request o.O

This invisible ability works up until a certain level of mob and some mob will have true sight.

That said you say "When are we going to be getting content with a risk and challenge?"

What do you mean? What type of hard and challenging content can a gatherer have? Taking in account that they can't fight and you need to consider that not everyone has a battle class leveled.

So again i ask, what do you suggest as a hard content with risk?
