The new layout for inferno is just incredible, the map really has a solid volcanic feel and is just fun, along with running smoother on my slightly older rig than the previous version.
The increased rock piles near mains on Clearcut are a great improvement. Didn't get to play a full round.
Wasn't watching the terrain enough on the short time I played the swamp map to notice changes.
Only had time to play two rounds on Inferno and partials for Clearcut and the swamp map so far, but very impressed.
