Patch 2.4 Notes

[Monkey]

If they put badges on 25-man content, and make bosses drop ~10-20 badges each and make each piece of gear cost at least 100 badges, then you have effectively done the same thing as requiring a different kind of badges. Lets not foget that the loot they would get in 25 mans would generally be more useful.

For those of us who obsessively click 'reload' on WoW news sites (I don't even play my 70 anymore. What is wrong with me?) on 2.4 news, these questions have been answered.

Every 25-man raid boss now drops badges of justice. At least in the Sunwell Plateau, they're currently dropping 2 each:

And the items cost between 45 and 150 badges:

Chest/Legs - 100 Badges
Gloves/Belt - 75 Badges
Rings - 60 Badges
Two-Hand/Caster Weapons (Including 1H Caster) - 150 Badges
One-hand Weapons - 105 Badges
Off-hands - 45 Badges

( from http://www.mmo-champion.com/index.php?topic=4450.0 )

If these numbers carry to other 25-man bosses, then a full BT/Hyjal clear is worth 28 badges per week, while a full clear of Karazhan will still only be worth 12 badges per week--the same number as running SSC. So the only reason to run KZ (or heroics) will be if you are currently clearing BT, Hyjal, SSC, The Eye, Mag, Gruul, ZA, the Sunwell Plateau, and still want to earn badges faster.
