Give premium members the DLC 2 or 3 months early before giving the DLC pack out to everybody. The normal 1-2 weeks is not sufficient.
I agree. If you are taking the plunge, and trusting that the addons will be worth your dough (in advance), you should get a bigger reward
My only issue with that is the player population. If the gap is too long it may effect the population thus limiting the experience of players who have paid for content. I feel like 1 month would be ok?
Yeah, one month I think would be the ideal amount if time
