Was thinking about it this morning, what if all the top guilds can't go on PTR? Everyone has to work on raids while they're live, it'll stimulate guild recruitment, teamwork and strategy. Right now it's mostly guilds that do the bosses earlier and then blast through 30% of the bosses in a day or so. Clearing the content will take a lot longer as well, while still being challenging. Just an idea, not sure how it would work in reality, any thoughts/ideas?
