Some good discussion happened on this topic both in my own previous post on the subject, and in a forum thread I posted today. I wanted to summarize some of the ideas that came out of it to prompt further discussion. I have not reproduced every idea; there were a few that seemed likely to be deemed too complicated to put on a tooltip, and there were a few focused on lifting the Crit cap, something GC has said they don't want to do.
Many specs have a soft cap on one of their secondary stats: an amount they try to reach and not go over, because past that point, the value of the stat declines significantly.
A quick note for those who have tried to contact me or ask me questions, here or via email or on Twitter: I'm not going to be very available for a while. You may see me spouting occasional stuff in a forum or on Twitter, but the vast majority of my brain is currently occupied with closing on a house and moving while preserving both my wife's and my own sanity. When the whole terrible process is complete, I hope to look back on my mail and other channels of communication and get back to people. Until then, please understand, and thanks!
There was a quick discussion on Twitter today about the question of whether or not it's reasonable to roleplay an atheist in World of Warcraft. The general thinking goes: magic is real, and we have tons of eyewitness testimony of the existence of beings such as C'Thun and Yogg-Saron, so it's not reasonable to roleplay a character who just outright denies the existence of these beings.
