honestly i dont get why people think that a gatherer needs challenges such as battle. they are not a battle class and you can't switch classes when you realize that you have been aggroed, you're basically a sitting duck without some kind of protection.

also with those systems you are suggesting: some imply that DoL needs to be similar to DoM/W, and some are to the exact same effect that the hide feature will have. regardless of wether or not these systems would work, are good ideas, or supply the "challenge" you are looking for. they are either not a resemblance of the DoL or would end up as the same function as hide
