Wafflekong said MOST - so clearly not referring to isolated extreme instances - the very first raid boss was very easy.
Fact is, in the past many cycles before it was changed, it was taking top guilds 2-3 days - not hours. I really want to see what waffle was thinking - my guess is he does not realize that normal is such a small percentage of Heroic - that's the most generous explanation I can conceive of.
