Guild Wars 2

We should be able to make small barriers anywhere on the map. They we be about 4 players wide and your able to jump over them but take damage for a kinda of razor wire i think this could be a good way to slow down and damage enemy zergs.

I was just thinking after playing WvW and getting truly confused with three commanders on the field. That you should be able to use the dyes you unlock with your tags so we can have more then one commanders.
