There’s that sanctimonious nonsense again.
Hive’Ashi is literally on top of the the base and the guards have a fantastic and long leash range, particularly if you kite them well. Using them to destroy your enemies and friends alike is hilarious, fun, and part of how PvP servers work with highly dangerous mobs. This is precisely how the Shattered Sun Offensive guards were used to great effect during TBC.
What is sounds like to me is that Hive’Ashi can be quickly overrun with a load of guards, so you had best be prepared for that to skedaddle, kite, or eat a death in a convenient location.
Welcome to PvP
You’ve hopped around but what you want is “fairness” on a PvP server, you know the rest of the quote you ignored? That doesn’t exist on a PvP server. You will be griefed, you will be overrun, you will have PvE elements used against you, repeatedly, and you will not get to do as you want according to your own weird concept of “fairness”
When you can find an explicit definition of “zone disruption” that gives zero discretion to Blizzard, you can claim something is absolutely actionable by Blizzard. Until then, you can kick rocks.
