I just came from one of those groups, where 3 guildies (since blizzard made it that doing a guild group gives more guild rep, it's more common you find 3+ guildies together), me and another pug, i found myself outvoted 4/5 people wanted to just skip to the last boss when there are quite a few nice drops off the other 3 on the 2nd floor. Blood of Isiset, band of life energy, legwraps of astral rain...all of those drop from other bosses and none from Rajh, and all of them are upgrades for me.
Perhaps in the next patch you could possibly set it up so you can't just skip to the last boss and you have to complete the other 3 first? maybe like poles of light like you see in uldum that connect to activate the stone statue of Rajh? I am tired of getting gibbed in getting gear, this i believe falls under the rules of regulation of "interfering with another person's playing time" or something along those lines...cause my gear basically is determined by 4 other group members, where I'd say about 60% of the time is a bunch of guildies and about 98% of the time, people want to just skip to Rajh.
Please fix this for healers, dps, and anyone else that wants gear off the last few bosses in Heroic Halls of Origination (it's not so much a problem in reg cause you don't get valor and i found alot of groups went along with it).
edit: just making sure...but this is where i was supposed to post this i hope?
