I am on Undermine (Horde) and this zone is unplayable. There is a huge lag between clicking on something and then having the box pop up to loot it.
It is most likely due to the amount of people farming Cobalt rep in the Cobalt Assembly area! So many groups on LFG and randoms in the area…I was there for an hour today farming rep and it was packed and really laggy the whole time.
