Quite a few people have stated in other threads that they were only going to spend money if they get the 90% off coupon.
I don't have any plans or expectations to spend money in the next 6 months, but a 75% or higher coupon would probably change my mind. I'm technically not holding out for one, I'm just waiting to see how the system revamps turn out and if i find endgame fun again. That's going to take some time
