Agreed on the Nadox porter. That would reduce some of the unnecessary traffic into/out of the zone. I'd guesstimate that roughly half of the lag I get in HoH is due to people zoning their massive box armies in/out of the zone repeatedly. It's clearly visible that when someone does this it sends a devastating wave of lag throughout the zone that lasts for quite a bit of time. You can see it by either having one toon parked near the entrance and watching the 18+ players zone in all at the same time, or by doing frequent /whos and watching the numbers before/after a spike. And I know that these people don't do it to be malicious. They do it because that's how they want to play, and HoH is set up in a manner that requires people zone into it frequently due to the instances/portal to nadox. But knowing this doesn't keep me from muttering under my breath "Do you really need to box 20 groups?!" when I get hit by one of those massive spikes

Heck, last night I was thinking that I really wished that you wouldn't be allowed to bind in HoH. Almost everyone who's t8 flagged binds here, simply for the reason they can mass TL to bind from inside instances to quickly get to another instance. However, this also means that if you wipe somewhere else with no intention of doing anything HoH related, you lag the zone without much reason. The only major drawback of removing bind from the zone would be having to zone an extra time to rush to that next boss, but that could be alleviated by adding a purchasable low cost (1k points?) clicky item similar to the vale token that could gate you back to the entrance.
