Lag is out of control in PvP

Any large team fight in instanced PvP, it doesn’t matter, the servers can’t seem to handle large scale pvp. I Don’t know how else to describe it other than ‘super low latency, high lag’

example normal:

World 62
Home 64

Instanced pvp:

World 62
Home 17

that home 17 is when the 3+ second delay hits

I know for a fact it’s not just me experiencing this
