I'm just going to say it's standard practice to stay away from the front of a gold fish as that is its main damage dealer most of the time (IE: Flak Fish, Lumber Fish, Hwacha Fish, Carronade Fish, etc.) As for the lumber jack, as said before, the arming time is exploitable, if you can get in close enough it will do little damage, best of all as I've already said attempt to avoid the front of the Gold fish at all costs.
