I think LFR is a good service to the game by allowing people to see extremely watered down versions of fights and of course seeing the Lore.
The biggest issues I have with lfr are
1. People have basically 0 accountability
2. Que times are horrendous
1. Offer tanks and healers some incentive to que, no the satchel is horrible. One idea is for every wing of lfr you tank or heal you can be placed in the front of the line as a dps toon.
You tank Vale of Eternal on your warrior
you then que for Vale of Eternal on your druid dps and skip the line
or give an increased loot drop for healers and tanks nothing major
or double valor for tanks/healers
As for accountability, the vote kick rule basically ensures every group will have trolls or afkers. People should be able to vote kick whenever they want. The dps in the SOO tier has been 20k-40k lower than it was last patch. If someone wants to roll in and do 20k dps than the group should be able to kick them.
