The announced 4.3 content patch presents us pugadins with an interesting question.
What will drop from the three new five-mans?
If the scaling runs as it has done, then the new normal mode raids will drop ilevel 397 gear. The five-mans, therefore ought to drop either ilevel 391 or 372 gear, given that the trolls drop 353.
I'd personally expect them to drop 372 gear as the instances are likely to explode in the face of puggers jogging around in an average ilevel 365 or so set.
The problem with five-mans dropping 372 gear is obviously that raiders hitting them in 375 or better gear have nothing to gain but their Valor Points from the very start. We won't even talk about hard mode raiders.
Later on that problem would become even more accentuated with raiders geared in 390+ gear running together with puggers in 370- gear. The difference in ability to handle the content should be astounding given a 20+ ilevel discrepancy in gear between a semi-decently geared raider and a pugger who has gained just about everything there is to get from pugging.
Of course a new quest hub, similar to the one in Hyjal, could rectify the problem somewhat. But Blizzard has only announced a new raid, and prior to Firelands they were pretty loudly sending the message about a brand new quest hub with lore, individually changing landscapes and new vendors with upgrades.
Obviously the Firelands raid would see some rather heavy nerfs hitting it to open it up for puggers. The announced Looking For Raid would tie in well with making more players get inside raids, which in reality means more players getting inside nerfed raids. That way 378 gear is theoretically within the grasp of puggers as well.
If this is indeed the scenario, then the hysterical buff to tanking threat makes more sense. While a 365 geared tank should be able to survive a five man with 372 drops, the same tank wouldn't beeven remotely able to keep threat from a competent 30 ilevels better geared dps.
