Tanks Who Constantly Queue and Then Withdraw Trying to Get in Progress Instances

[Amyas]

Again, you are flat out wrong. It can and does hurt people's queue times. While that abusing tank is messing with Party A, a non-abusive tank comes on and gets put in Party B because the abusing tank happened to be in-between withdraws and the system thinks that Party A has been filled (it can't predict that the abusing tank is going to withdraw in a couple seconds).

And how do you know this happens? What proof do you have? Its possible I'm sure, but I'm 100% positive this isn't the case 100% (or even half of the time...) of the time when there is perpetual withdrawals.
