Back tot he topic at hand, I would seriously love to see this sort of change. It is impossible for Blizzard to make the two difficulties the same. All they end up doing is separating the community. 10 man guilds are the most progressed on my realm. Of course they all insist that simply makes them better because 10's are harder than 25's right? They must be, since Paragon switched.
Switch it back to seperate lockouts with seperate loot levels. Guilds can go back to 25 man if they want. They can get better gear for putting in harder work. Guilds that can't recruit, can stick to 10 mans. The gear they get in these 10's will be sufficient for the difficulty they are attempting. the only reason 10 man guilds felt compelled to run 25's on top of 10's was to get better than 10 man loot because they didn't have the skill to down the encounters with the intended loot.
