New dust 2 map or old dust 2 map?

I dont really know why everyone is saying there are, "errors" with the new dust... The truth is the new map is better optimized, less glitches, and it just looks better. Not only did they make it easier to learn they added stuff for more experienced players to master. There will always be shit in a map they breaks. I mean there is still an invisibility glitch on nuke. The new map is great and it eventually people will see that.
