no offence but you cant tell if some ones discos before battle has began? 
Before battle has begun, the fields stay open for the first 15 minutes and a disco can re-up anytime without asking. In fact, if you arrive after fields are open, as long as it's in the first 15 minutes and you show on the roster with a registered squad, you can take off no questions asked. From T+15 to T+30, as long as active combat hasn't begun, we will open your side's fields for a disco to re-up. Once combat has begun and enemy forces have inflicted damage, the fields will not be opened again.
Regardless of the rules and procedures we follow, the disco reconnect feature built into the game should put a disco'd player back into his plane no matter the time or status of the fields. I've seen many players be successfully put back into their plane, while other players might not. We do not control this feature's function, other that having the ability to enable or disable it for the whole arena. We have it enabled the whole time and never change it.
