Your logic just...does not make any sense. We are saying to nerf 25-mans so that they become more attractive. If you nerf 25-mans and 10-mans at the same time then nothing changes.
The problem at hand is that 25-mans are harder to assemble, but are the same difficulty as 10-man and offer the same rewards. Thus 10-mans are the best option for people not willing to deal with the logistical hassle of getting 15 more people. If you make the difficulty of 25-mans substantially easier compared to 10-mans, then people would be more willing to deal with the logistics of raiding with more people, because bosses would die a lot easier and loot would be gained a lot faster.
Can't you see the possibilities that arise from separating the difficulty of 10-man and 25-man raiding? Right now Blizzard tries to make both sizes equal in difficulty, which is nearly impossible to the fact that having 15 more people just makes things very different. So either 10-man ends up a lot easier, or a lot harder. If instead Blizzard was to focus on making 10-man the top of the hill as it were, then they could switch up mechanics and make them specific for a 10-man raid.Why would anyone want this? We have NORMAL modes for the average crowd, and HEROIC modes for the elite crowd. Why complicate matters by tying raid size to the difficulty quotient?
BTW, if you believe that the average crowd doesn't raid heroics then you're mistaken. My guild is pretty much the definition of average, and we always enter each tier with the intention of making it to the last boss on heroic. Heroics have become so nerfed and watered down that they're just slightly harder versions of Normal mode.
How can you say whether people really want it or not? The OP put forth suggestions on giving a proper incentive for 25-mans. There are two people at least in this thread that have argued for 25-mans being nerfed and 10-man becoming the new Hardmode standard.The OP does not desire that. No one on this thread really wants that. Are you actually serious or just trying to play devil's advocate for the sake of it?
I don't see that happening at all. LFR is markedly lower because it's so ridiculously easy. We're not suggesting that 25-mans become LFR difficulty. They should just be easier to defeat because the logistics hassle in itself is part of the challenge. You would still need to pay attention for 6 minutes and follow a strategy.But simply buffing or nerfing one the raidsizes is definitly not the way to go. We have 3 difficulties with LFR, 10/25 man normal and 10/25 man heroic.
Also, as we already have LFR, do you really think 25 man would become so much more popular? Also, if they would nerf the difficulty, Blizzard would probably also reduce the item level, resulting in a reversed WotLK situation.
