@Xinek Not sure yet. We'd like for it to be sooner though. We want flex to seem more attractive to someone on the fence.- Greg Street (@Ghostcrawler) July 13, 2013
Ghostcrawler's approach certainly seems to make sense. By pushing the new difficulty out sooner, more players will be enticed to give it a go, and hopefully more will like it. However, the downside for this is of course the hardcore players, who might feel even more obliged to take on the new difficulty for gear if it's rolled out sooner. However, they are such a minute percentage of the player base that it seems illogical to excessively punish the rest for their benefit!
What's your take on this? When should Flex appear? Personally, I think I'd like to see the first wing release at roughly the same time as heroic, and then a wing per week until it's all out. I think Raid Finder should probably follow about a week behind that. But this is really just personal, and maybe you feel differently? If you do, then why?
