I have no idea if what I am about to post has been posted before but here goes.
I voted for an easier 10 man, with that i think there should be a heroic scenario like option. What this means is that there will be an option to queue for a 10/25 man raid (I am not sure if 25 is doable as well). The group as to be formed before queueing which is the same as the heroic scenarios, you can not random queue if your group is not complete. This raid will either be on the same difficulty level or higher. I personally would like to see a higher difficulty, pretty much between LFR and Normal modes (again I am not sure wether this is possible or easy to set up). This way raiding guilds who are stuck will be able to get more practice for when they take on the normal modes without getting hold back by the LFR "noobs". As for the loot dropping inside it could be taken care of the same way they do it in LFR, a chance on loot or a bag of gold. The only exception I would make there is after killing the end boss, Lei Shen, you receive something like the cache you receive the first time you complete a heroic scenario and hand in the quest. This will be more rewarding for killing the in between difficulty for guilds. The item level of the dropping items could be the same as heroic scenarios as well. Its not Normal ilevel but close which will mean guilds can take on normal modes easier if they are geared up a bit.
What I believe should never and I mean never ever happen is difference in ilevel between normal 10 and 25 man. From every aspect this will not be fair to the 10 man raiders which I believe nowadays take up a great portion of the raiding community. The fact is all other activities outside of raiding, take brawler arena for instance, will depend on gear as well a skill. Being in 10 man normal raiding guild will eventually not give you the same gear as a 25 normal raiding guild but you do need the same skill level. See how this leads to a new gap. Also it is impossible for some people to raid in 25 mans even if they wanted to and pugging is pretty much not an option.
These points are what my views are concerning the given options. I myself would not change anything about the current set up. Why you ask. Well because of the following, with the starting of Dragon Soul we got to raid on 3 different difficulties. This lead to the majority of the people getting to see all of the content the raids had to offer. This makes it sound like a major enhancement for everyones gameplay. It is. Then why do we have to get yet another difficulty. Everyone already gets to meet the new content through LFR, then why do they so desperately need to clear normals. If you can not do it reconsider going at all. Im not telling people to get out because they suck but its a game, not every difficulty should be reachable for everyone. If they make everything puggable its just a matter of time before people will start complaining about heroics being to hard to pug. I call this the egocentric view, everyone wants everything. Well just like the REAL world, it should be like this: YOU CAN NOT HAVE IT ALL! And just like the real world there are always people who will.
I myself have not cleared any heroic yet, this because I have not been playing much lately and my guild has about just enough people to raid on set days. Meaning if someone does not show up we will not raid. I have as a matter of fact cleared normal, which seems is not that hard so whats the fuss all about?
