The merch giveaway tickets should be purchasable with loyalty points. This would reduce the "only for the giveaway" -attendants. At the moment ALL viewers can only get 1 ticket each, although subbies can get x number of extra tickets (decided by the streamer). That way those who have been in the channel for a longer period could also be able to buy tickets. There should also be a roof on all the tickets that the streamer can put, for example "Maximum number of tickets: 3"
