WoW: Perspectives on the raid lockout system

Even with a week that was jammed to the rafters with non-WoW issues for me to deal with, I paid attention to the news, and one of the biggest stories was the news that Korean realms are going to split the 10 and 25 man raid lockouts in patch 5.1. Now, I have opinions about this, because despite my notorious preference for 25 over 10 man raiding, I'm not completely behind this change. I was surprised to realize this, actually, but reading the announcement got me thinking.
