Hi, just noticed that you can query chars below level 80. Very nice. But is Caverns of Time really harder than the oculus or halls of lightning with the boss who kills the most players like Blizzard said? (Loken) Maybe some of the 77+ instances should be rearranged?
Halls of Lightning ,Utgarde Pinnacle, The Oculus and Caverns of Time are 4 instances preferable for lvl 80 players like its said on the tool tip (mouseover instance bar ). How hard that instance will be for you depends of the group.
