duo fungi king in water at ledge? exploit or no?

[syztem]

no drop fungi sounds good to me, easy enough to key and park a level 1-60 alt down there to loot it. just curious if anything will be done about it, so far been able to run these guys off with a few rogues since duoing the PH let alone the spore king is hard enough as it is. But on red if no one is watching they can easily farm fungi's for 8hrs+ uninterrupted. Just really want an official wording on it if its allowed now, or these people are just getting lucky by doing it when no GMs are around.
