Right now, a good 90% of the active playerbase still has upgrades they need from Raid Finder, including current raiders. This means quicker queues and better groups overall. Once those raiders have their gear, though, will they continue to participate in the Raid Finder?
With gear levels topping 380 and the heroic 5-mans reasonably easy, those seeking quick valor will likely end up there instead of the Raid Finder, which demands a larger commitment with less chance of reward. Two months from now, I'm afraid the Raid Finder queues will be full of nothing but alts and occasional players, causing the situation from the PTR all over again. What do you think?
