If time is your main obstacle
at a set time each week
You do know that these are opposites, right? I like on-the-fly gaming, and suggesting that if I want to do on-the-fly gaming I have to temporally constrain it is just completely oxymoronic.
No, the OP said he didn't have much time, so the queues he was experiencing meant he didn't get much actual raiding in. Arranging a set time to log in and begin raiding immediately, as I suggested, may be beneficial in his case. However, if you don't know when you'll be free to jump into the game, then obviously the suggestion wouldn't be ideal for you.
How about further incentivising Tanks/Healers and turning the difficulty knob down some more in LFR to reduce time spent in there, instead of trying to kill off the very tool propping up raids?
We do monitor feedback on the difficulty of LFR and we adjust accordingly—we've made changes
since SoO was released. But which do you think is better, that the overall difficulty drops because of wipes, or people try to learn the encounters and step up to the challenge?
