Genie is out of the bottle. They've sued Bossland and lost. If you think they're going to just forget HB exists because they disable PvP you're lying to yourself.
Blizzard isn't some kid holding a grudge. It's a massive company. I'm not saying they're going to forget HB exists but if we stay out of their way they have no reason to waste time and resources banning us. If instead we spoil pvp virtually to the extent it's unplayable for normal players, then that's going to force them to do something. It's just business to them; that's how you need to think about it. I really don't see why you're not understanding this, it's pretty simple.
