I disagree with the lockouts being shared

I totally agree. Especially considering the reasoning behind it:

while at the same time stating:

I feel that there might be 1-2 weeks (give or take) that a guild might be trying to run both, but any Heroic guild will quickly move past Normal for raid nights, and the raid team can/will PuG normal if they so desire, which is exactly inline with what they’ve stated the want.

Personally, I find this change to be much more impactful than the Dungeon Finder change, but it doesn’t seem that many people will make noise about it.
