Why is it OK to have multiple bosses spawned but not normal force spawn NMs?

If two people are spamming trade macros and one lives very far from the server and the other lives close to the server, then the person close to server will get it every time. That is not difficulty. It's an imbalanced road block.

This is true. no matter how fast your machine is you can't out pop an average JP popper. The other night, I wasted almost an hour just trying to pop a Kharon against 4 JPs. I could only pop it after they left. This frustrated me to no end.
