In progess LFR queues solutions/suggestions

So after sitting queues for all 4 Throne of Thunder wings, and then a Vault of Mysteries queue, and getting 4 out of 5 of those queues at the second or third boss of the wing, I'm a bit annoyed.

It got me to thinking, Blizz needs to make a special incentive for sticking around and clearing all 3 bosses of a given LFR wing, so as to minimize the frequency of in progress queues. Let's face it. A 40 minute Lei Shen queue sucks. A 40 minute reque for the wing sucks. But getting a mere 45 VP after wiping 3-4 more times on that second Lei Shen kill really sucks. (other wings it's just a mere 45 VP for sitting through 15-30+ minutes of one boss or two bosses you've already killed and won't get loot for killing again)

I was thinking that if you get a fresh queue, and stick around for all 3 bosses, you get a special bag that has a 100% chance to contain an item (specific to only your class, not spec) from the shared boss loot or trash drop loot table, in the case of ToT, and one random item from any boss in the wing, in the case of T14.

To me, this idea would give players a much better shot at some loot that is currently at ridiculously low drop rates, and provide fresh queues more often than in progress ones.

I want to know, has anybody else been affected by in progress queues? Does my idea sound reasonable? Or are there better solutions?
