I had a thought about adding an additional boss to the mix on our shard. A Water Boss.
Either spawn as a champion in the lowest level of Shame (on the water) having to use the islands to fight and move about or Out in the open sea, using a boat to get to. Now boat stuff is tricky as people have a tendancy to trap with multiple boats etc, but perhaps can define a zone area in the ocean that scans ever 30 mins for a boat and if no player mobiles are detected, shipwrecks and destroys the boat.
Otherwise, leave it in shame and have it capable of summoning Krackens and Levithan's on the water, and Water Elementals on the islands. Earthquake attack in shame where it "graps hold of the island and shakes it virgously" causing damage or a Tsunami Wave on the open ocean. A water gun attack is a must i would think etc.
There is lots one could do with it. I know we have some great bosses, some i've seen before on other shards, others i haven't..but if anything I'd say Shame is due right for a champion....poor left out dungeon.
