Removing that dispel case from context looks like that. However as you yourself pointed out earlier, it was a culmination of miscommunication during a few floors. And while I say miscommunication, yes, I say it was going on both ways. If I got your original post right, your friends had slammed their help macro to them, while the gate was already open. I understand how it might have been valid help calls from your friends point of view, but consider it might have gone like this.

Gate is open, people head on the gate as is usual from most of their runs. Someone says help, to which they say ok, expecting those said persons being pulling things that bite them to the gate. They wait because that's how they are used to act in such situation. Yet your friends keep spamming the help macro without heading towards them.

That in mind, they might just as well have though your friends were trolling at that point when they asked "what" to a dispell request which, by this thread response, seems to be obvious to everyone else expect you.
