@Featherkin Varied layouts, but aiming for nonlinear where possible. Highmaul layout resembles Firelands; Blackrock Foundry more like ICC.- Watcher (@WatcherDev) February 12, 2014
We can see the map for Blackrock Foundry above, and understand what Watcher means with regard to the ICC-esque layout. The circular room at the top is likely to be the room you're looking to unlock by completing wings. And a Firelands-ish layout has much the same effect on raiders. While the world first progression guilds will dislike it, as they thrive on assessing who's behind and who's ahead in the race, they're a tiny percentage of the total raiding playerbase. For the rest of us, it's incredibly frustrating to get stuck on a boss, for whatever reason, and feel like there's nothing you can do but repeatedly throw yourselves at that same encounter.
