Tosh. Complete and utter.
The *cheapest* of the new rewards is 60 badges, with 75 for a few items but 100 for most. A complete Kara run nets (I believe) 22 badges and can be done once a week, and heroic provides 3-5 (+2 if its a daily), none of which can be said to be "easy mode". At best, running 2 heroics a day and complete clear of Kara you're looking at circa 60 badges a week but that implies a level of gear and commitment that suggests you'd already be in a raid guild of sorts - I know that realistically I'd only be looking at 20 or so badges a week (assuming the guild does heroics that week and can muster enough people for a raid) - so between 2 and 4 weeks for a bit of kit (the mage stuff needs about 550 badges, which is 3-6 months work).
Now, the complaints I could understand to a degree, but the exagerations used to decry the badge rewards are, to my mind, undermining the credibility of the opposition. "I can get 100-200 badges a week so this is OP" says one guy (really? How? You run 35-40 heroics a week?) "Its ez mode because we can clear Kara in 3 hours" (in T5/T6 gear, maybe, but in that case these rewards probably won't interest you ... and you can only do Kara once a week).
Then again, there are some valid points "These are better than MH/BT drops so why do MH/BT" (if these really are better - and I don't know enough to say - then might it not prompt some people to switch away from the raids. I don't know what the relative incidence of 25-man raid loot is, or the comparative quality of the items.)
That being said, I still think of lot of a "disagreement" is more in lines with toys being thrown out of prams - I mean, how dare the "casuals" be able to get loot similar to the "hardcore"? In actual fact, a number of "casuals" I know but in more time and effort than supposedly "hardcore" raiders, so to my mind why shouldn't that pay off with decent loot. It's a lot of work (certainly moreso that Arenas and BGs and this kit is the same itemlevel as the Season 3 rewards), but looks to reward "time invested" (in badge awarding instances at least) rather than "raids attended."
YMMV, obviously.
