I only raid 25 man so getting rid of it would be the end of wow for me. I personally enjoy raiding with more players even if that means we have to carry 1-2. Maybe my 25man raid is a bit odd but I feel like it is a very tight nit group and at times can feel as 'close' as a 10man but that's from the amount of time we've all been raiding with each other. I don't want to see the raid style I prefer go away just because some people don't like it or think it's pointless (I could -very- easily say the same thing to a 10man raider).
Possible solution for 25man:
Allow a boss kill to drop one of the BOE items from the trash (excluding patterns) or an increased possibility to do so. The trash loot drop rate is already kind of bad at the moment and when you have 3-4+ people complaining about wanting their bracers and/or trinket that finally dropped after months of work (and you've only ever seen that item once) can get a bit intense.
