World of Warcraft Reputation Guides - Cataclysm Redefine Raid Progression Guides
Having the same difficulty between 10 and 25 player raids has been something long asked for by what seems like a growing portion of raiders that really enjoy raiding but don’t enjoy organizing 25 people. I count as one of those type of raiders, and for a long time avoided large raids once 10 players were introduced, just because of the complications they bring. There are many players that want a harder more challenging fight than the current 10 player raids provide, but are not up for interacting with an addition 15 players.
One of the positive things about sharing loot exactly though is that in theory Blizzard will have to produce less loot and therefore can spend more time on different looking and acting loot. Right now a lot of time is spent balancing two different levels of loot and trying to make them different enough for the different content. Now the loot can be the same because the difficulty will be the same.
One decision that may need to be reversed to ensure 25 player raids stay active is the single lockout. Many times right now players use 10 player raids to help gear up new players so they can come to 25 player raids, or to teach new players the mechanics. If this option is gone on a weekly basis it may be harder to teach new and casual players the content, or get them up to speed to participate in larger raids.
