Apparently people dropping out of random Oculus runs has been noted. I know it happened to me the other night.
Blizzard: Run Oculus, win fabulous prizes:
Despite the nerfs in Patch 3.3, it's pretty obvious that whole lot of people still hate Oculus, enough so that they immediately bail when it comes up as a random dungeon. Apparently, it's a substantial number of people doing this, enough that Blizzard's taken notice and taken action.
But they're not removing it from the system. Instead, they're incentivizing it -- or, if you prefer to be a bit more pessimistic, turning final boss Eregos into a loot pinata in the most direct way possible. Zarhym's announced that those who happen to get Heroic Oculus with the random dungeon finder and stick it out to the end will find their own personal loot bag in Eregos' cache. The bags will contain two extra Emblems of Triumph, rare gems, and a chance at the Reins of the Blue Drake, formerly the rare mount drop from 10-man Malygos. To make up for the switch, the Reins of the Azure Drake will have a chance to drop from both 10-man and 25-man Malygos.
Will this staunch the exodus from Oculus? Will the lust for yet another pretty dragon mount inspire people to tough out the dreaded vehicle mechanics? Or will people just tough it out until they get their drake and start group dropping again? It should be fun to see what happens.
