What innovation do you think should come to CS: GO?

Like a new map, weapon, continuation of Source 2, improvement of VAC protection.

getting source 2 into cs: go will be sooooo much better, improved physics, better audio and graphics, all kinds of thing

By the looks of a few posts here it really seems like kids would benefit from a sprint key. XD

Id like to see a reboot on a new engine, it would breathe life into the series and give us a way to transfer existing achievements and skins etc.

New gamemodes and weapons - This will definitely diversify the gameplay.
