For example, the owner of the mask (and potentially his group)will always receive the maximum effect of the xp buff. For everyone else that the buff lands on, they receive a random do buff, something between 100% - the maximum effect, assuming the mask is above the 100%xp threshold.
Anything under 100% could be randomized between 1% - the max buff for simplicity, or simply make it so that anything under 100% is self and/or group only. Once you reach 100% the mask is then mgb-able with anyone outside of your 6man group receiving a random amount of xp through the buff.
That would certainly slow down the xp gained for anyone that does not have the mask for themselves, but still leave the owner of the mask with the full benefit, it would even slow down people that box multiple groups as they'd have to decide who they want to recieve the full effect of the buff, the others would still gain an xp buff, but it would be random so there's a chance that they only recieve an 238% buff instead of an 830% buff. While here's also the chance that they're lucky and recieve the full 830% still.
Not sure how feasible that would be from a coding standpoint, but it's another option that might be accepted by a larger majority or players (hopefully)? Sent from my phone, will proof read and edit typos later
