My educated guess is that we will have no more than 3 weeks of Flex raiding left before 6.0 drops. If I am reading the changes correctly, that means after 6.0, the following will occur:
Gear itemization will change, possoibly changing how we perform
Class abilities and rotations will change, possibly changing how we perform
Seperate dungeon wing instances will be gone, forcing us to clear the entire raid prior to each Garrosh kill
We SHOULD be able to resume using lockouts, so if we clear through Nazgrim (for example) on one week, we can start on the following boss the following week.
This may cause issues for players who have a regular raid group, as we will now be a "normal" difficulty team.
So in planning ahead, I need to know who will be continuing to raid with us and who will be saying farewell. Remember that if you wish to commit to the WoD Raidy Brunch team, you will need to change your server if not on mine (Kazzak), so that we can be treated as a real team and get the benefits.
I would really love evveryone to weigh in on this so I know where we stand.
