Siege of Orgrimmar Raid Testing
I will test this out with my guild this weekend, I'm sure, but why exactly are we getting LFR testing instead of Flex? Why is Garrosh not active in LFR testing? If Flex comes available this evening, will Garrosh be accessible in that testing environment?
We don't have plans for additional Flexible testing. As for Garrosh in particular, we want him to be defeated for the first time on the live servers, where it counts. In the past, several final bosses such as Yogg-Saron or the Lich King were never publicly tested on any difficulty at all, for just this reason.
As for Flexible tuning, we're satisfied with the current state of tuning for the first three wings, and we can heavily extrapolate from Normal tuning and how that plays out when it comes to nailing down the Flex tuning for the final wing. Flexible mode has much, much more in common with Normal than with Raid Finder -- all mechanics are present, the zone entails a gear and difficulty progression, and so forth. In the case of Raid Finder, on the other hand, specific mechanics may need to be profoundly reworked or removed entirely to accommodate the dynamics of randomly matchmade groups, so making sure that we see as many fights as possible in LFR on PTR is a priority.
