Well, this was certainly unexpected. I certainly didn't expect things to change in such a drastic manner. And frankly, I'm not entirely sure I approve.
Take whatever side you will on the 10/25 divide, but while I primarily raid 10-man, I learn mechanics in 25-man. I feel that it's easier when you have additional people to pick up the slack when execution fails, and to have the full set of raid buffs/debuffs at hand allows for greater tolerance in... well, greater tolerance in fail.
I'm not completely against these new changes? And I won't make any judgments regarding smaller loot tables = less betterer itemization, because itemization is changing for everyone. But it's an interesting thing that they've put here.
Still, though. Temper your reactions, this is still Blizzard telling us stuff without actually telling us anything, again.
There are altaholics.... and then there's the rest of us. A Druid blog for the player that never wants to have to roll another character again. A Bear/Tree/Cat blog dedicated to being able to queue for all three roles in the Dungeon Finder.
