Ok let me explain this out a different way. The only reason I mentioned plvlers is because the buyer for the advertised plvling groups on this forum are at great risk for a suspension if they're buying a plvl from a seller that's boxing more than 2 toons. Hence my "just be careful."
Let's forget about the plvl thing for a second. If the people in seb playing more than 2 characters at the same time, then we're literally talking about the same thing. They're breaking the true box ruleset. Whether or not they're using macroquest, or pulling the entire zone at onces has nothing to do with this. It's just about boxing and getting suspended for it.
If you're talking about 3 different people all boxing 2 toons, then yes, we're talking about two completely different things. And yes, I understand you're talking about zone disruption, fucking up the economy, etc. But the only way a single person is able to do this is by boxing all of these toons at once.
Some of these same guys are selling plvling from 40-60, but you have to be present. They're outside gangrenous scarab cells, claim ABC, pull everything into that room, stun with chanters, aoe everything down. I know exactly what you're saying. They're taking a break right now.
Hope this clear it up.
