Seems like about 8pm eastern is when it gets really bad - when more people log in. Zoning takes up to 5 min. Other functions such as invites which should be instant response take way too long. Please prioritize this.
people are still arguing about this but frankly i think its clear that we need weekly server resets at least until they improve the lag. lag is bad because we had an early patch in march for anniversary and it's been a month since a reset
