Large World PvP Teams in Legion

[MultiBear]

...but where do you draw the asshole line?

I don't think it's (just) a matter of numbers. I'd say you've drawn it pretty well yourself (and stepped over it) in your original post when you stated this:

I was unable to lock down quest hubs due to the number of Alliance in the area, and I imagine 40 will fix that pretty quick

Your goal seems to be to cause such disruption all by yourself. Something which, as MiRai has stated as well, is a far more dynamic thing when it's done by a group of individual players given the amount of effort involved.

In my book, this is the kind of crap that gives multiboxers a bad name.
