The best "Levolution" i ever encountered was in Battlefield 3 Damavand Peak on Rush.

That's not Levolution. That's map design.
One thing that pisses me off is the fact that DICE has all these extra vehicles they add to the DLC maps and NEVER FUCKING USE THEM in other maps. Same for modes. I want CTF on Seige of Shanghai. Can't fucking do that.
