A. Blizzard wouldn't catch on
B. They would get away with it.
C. Failed to remember that, Blizzard keeps a very close on the raids on patch launch for this very same reason.
Every patch has its bugs and 4.3 was no exception apparently.
When 4.3 hit last week, the Looking for Raid feature brought joy to many pugs and now it's also now bringing misery to quite a few hardcore guilds. As it turns out, there was a loot bug with the LFR system and master looting. Instead of reporting them, however, most people chose to exploit it to keep their competitive edges. Members of many top guilds in the world such as Paragon and Method queued up multiple times through a loophole that allowed them to get loot again and again. While LFR is supposed to limit players to be eligible for loot only their first run through, this loophole allowed them to repeatedly farm for early tier 13 bonuses to give them that extra boost in PvE content.
The end result? Many players opened their emails to find themselves with an 8 day ban, just in time for the holidays--and progression farming. Heroics unlock this Tuesday and this was going to be the last epic push for progression hardcore raiders before Mists of Pandaria. Now many of these guilds now have entire rosters banned, along with their new gear removed. If the bans stick, this should greatly affect world rankings this tier.
Blizzard has yet to release an official statement, but hopefully they will soon.
So what do you think? Did they get what they deserved--or is an 8 day ban a little too severe for some 384 ilevel loot? Did you exploit or do you know anyone who did? On a personal level, a lot of my friends were banned, so this is turning out to be an interesting night.
