Kiln Cistern Raging Water Elementals and 5 Stars Area Indicator

I think the 5 skull indicator doesnt really reflect the real difficulty of the area. At combat lvl 60+ it takes 10 mins in about to kill a simple water elemental and raging water elemental is an endless fight. Same time going to 5+skull areas I can get kills a lot easier and generally I can advance the area. My log says "this task should be easy for me" though and if you add its 5 and not 5+ skulls it misguides people into thinking its a doable area alone. The main reason is they usually heal 110+ hp and do it 2 times in a row, pause around 5-10 seconds, and heal same again. I suggest you raise the difficulty indication to 5+
