Yeah I mean we do have Gem of Faith as well that 100% gives a random item at +8. People could buy that and take the risk of obtaining a +8 or just buy the (+5) or (+6) and take the risk of upgrading.
I honestly like this idea way better than just straight out (+8) in PUS. There is a reason why too. Donors wouldn't be OP day 1 and we'd have a constant $ flow for the dedi. Our dedi is around 500$/monthly.
Not to mention people wouldn't get bored as fast as just getting (+8) straight up.
