For everyone reading, this is in reference to: http://us.battle.net/wow/en/blog/4326384/Dragon_Soul_Difficulty_Changes-1_18_2012#blog
Believe it or not there are actually guilds and raiding groups that are attempting to progress through Normal and Heroic raids, but are hitting a wall, and have been hitting a wall. We have actual statistical data we base our changes on, we know exactly how many people are clearing these raids each week, we know exactly how many people are able to down just a few bosses, and how many were only able to down a few bosses every week for weeks on end and then stopped raiding altogether.
The issue we're constantly trying to combat is the one where people feel like they're just out of options. One way this is an issue is the content is too easy, they blasted through it, have everything they could possibly want, and have nothing else to do. Ideally that's a small subset of very hardcore players. For everyone else it's a feeling of just being stuck with no possible way to progress. Very few players are willing to suit up, buff up, do all the necessary requirements to raid, jump in, and then do no better than they did last week for hours and hours, only to return next week and do the same.
If a guild doesn't want the help, they're free to opt out of the buff. For those that do it's an approximate 5% change, which is pretty minor, and we expect it to be about a month before we raise it another 5%. This first change will absolutely help the guilds that are just barely sc@%#!*# by, or just need a tiny bump to cross the next hurdle, but it's just not logical to exclaim that someone will roll into Raid Finder, grab a couple items, then be looting Heroic Deathwing's corpse the next night.
We feel the content has been out for quite a while now, that most people who have progressed and downed Deathwing on Heroic have done so, they've had sufficient time to celebrate in their accomplishments, and these very small progressive alterations will only help guilds that are already doing well in the raid get over some hurdles they may be facing.
