I think "Battle for Gilneas City" is going to be pretty outstanding venue for new strategies. People can qq all they want about blizzard not putting a lot of original thought into the "first person shooter"-like style of map and play. But the map seems very clean unlike some AV towers and cliff sides.

While Blizzard obviously is leveraging what they already have on a map that is very accessible and popular, it seems that people really like maps such as fighting in the Stratholme map 10 versus 10 on private servers gate to gate and the Ironforge map.
