Disclaimer: "you" generalised.
For the record, I pretty much agree with everything Purr has said.
As someone with a hunter main, druid tank alt, and priest heal alt (amongst others), I certainly think the goodie bags are an excellent idea for tanks or healers who have to pug. If you have not experienced tanking or healing in a level 85 Cataclysm heroic pug, I personally feel you're unable to really appreciate exactly how stressful it is. If you are lucky, you'll get a good tank who is reasonable to heal (or uses CC), a nice healer who can manage their mana, and three DPS who stand in the right places and respect the wishes of the tank and the healer when it comes to CC. How many times have I ever had a heroic dungeon like that? Perhaps once or twice. Tanking and healing in heroics is *hard*. It's not just unpleasant or bothersome, it's truly difficult - even with "good gear", some pulls or some group makeups struggle.
The extra valour points suggestion has been shot down a couple of times but I'll repeat: if you want to get good tanks and healers, there is no need for additional valour points. I've been selling off the VP boots on my toons because I don't need them and I don't want them... even more so when the remade troll heroics come out and we can get even MORE valour points. The boots are already selling piss cheap on my server... We don't need more valour points. Just because your particular guild or friends or even in some extreme cases server (though I doubt the latter) is behind as far as valour rewards go, does not mean the rest of the 6 million WoW players are in agreement there. Anyone who is considered a "good" tank or healer (aka geared) at this point in game will have absolutely no need for valour, not even for offsets (who else's guild is disenchanting more epics from raids than they actually use?).
I don't see the reason for a huge flare up in regards to mounts dropping. This change isn't exactly going to make them common! They're still rare, still hard to get, and you're still much much more likely to get the mount drop from farming the instance than the off-chance you will a) complete a full pug heroic, b) get your goodie bag with a mount in it and c) it is a mount you don't have/want. It's still very minimal. If you have farmed mounts before you'll know the drop rate chances. Sure, there's a possibility Joe Blow will rock up, pug a heroic and get is white chicken in his first goodie bag: just as there's a chance you'd get it first run too. It's chance.
Sure, I've managed personally to handle the long queue times. I either ask a guildie to tank or heal to reduce queue times, or I'll use the 30-45 min queue to have a shower, eat, clean, tab out and do other things... Very rarely will I just sit there and stare at the game waiting.
But if I instead can't run with guildies and get to wait for 5 minutes, with a similar amount of luck in regards to a good group or a bad group, either kick the bads or pull them through (which I have to do 95% of the time anyway), can finally complete the run and go on my merry way, I can use the additional half hour I would have had to wait to farm for that mount I want!
So yeah. I'm really quite happy with the BOA thing, possible rewards etc; if I get Anzu again or something my Druid can have it, if I get white hawkchicken my hunter can take it... I'm content. I'm more interested in seeing the list of mounts we can get from the bags! My Shammy would have loved the blue Occy drake but it's essentially impossible for her to get now... That'd be really cool
