Before i start, i would just like to say. If you want to encourage teamwork in the Raid, teleporting 3 random players instead of those waiting at the back is not the way forward. Though i agree with patching the Atheon cheese and other things you mentioned, i feel teamwork was brilliant when organising who would go into the portal and who would defend back home... I would also like to suggest raising the level cap in the upcoming DLC in order to create an incentive to complete the Raid and receive NEW raid gear with different characteristic abilities and different looks. This would ensure we do not waste time pointlessly defeating hordes of enemies for equipment the same as those we may be bored of by the time this DLC is out. I know some may or may not agree, but this is just by opinion. Take it with a pinch of salt.
