Warlords of Draenor: Flex scaling to 30 "still on the table"

I'm one of those people who hates leaving people on the bench. I hate it when I have to step out myself, hut I hate it even more when someone else sits for me - it just irritates me. So I'm very interested in this tweet from Ion "Watcher" Hazzkostas. When asked if the idea of flexible raiding going up to 30 people, he responded:

This makes me very excited, especially with the change to Mythic raiding (20 man total cap) meaning that some current 25 man groups are going to have to bench players once they make the step into Mythic - I do, however, hope a little downward flexibility is also introduced at some point to allow 10 player raids to progress when that one key player is unavailable.

I'd like to see this change actually get implemented - here's hoping we get it by Warlords of Draenor release.
