Oh no we're not about to do this auth against user ordeal for a second day in a row so before it turns into that again-
Kami do you know how to add a poll to the topic? We could use that as an indicator of how many people feel a change is necessary as opposed to those who don't. I think it would be a good start should this be pursued further. If more people think the tiers are fine as is, then they might be; if the opposite ends up being the case, it's a good sign maybe something actually is an issue.
Once that's decided, if nothing else, we can use it for any discussions that happen with the advent of X and Y later on.
On the topic of getting to #1 so easily, it could be argued that the team makes it too easy, but at the same time I would venture to say that player skill is actually the biggest factor here. I personally would probably perform miserably if you were to give me the team that was used here, if only until I got used to it, anyway, and even then I'd get stomped by the people who know what they're doing. My point is, I think it's more than just the auto-pilot factor of the team(s) in question.
