Donation Suggestions and Ideas

[Kiwis]

VIP accounts

For a set price (15-20$) a month you get perks like maybe increased exp rates (not drops) and maybe unlocked warper.. also could do like a reward for milestone marks (3 months 6 months 1 year)

imo, might be too p2win for the most part, since its a singular, but quite large reward. And, heRO's always been about avoiding 'VIP accounts'. However, I think a more suitable option could be a combination of two of your suggestions,
maybe have a milestone exp boost serverwide, for every set amount of donations received, through any service/donation.
I understand that this may reduce motivation to donate, individually, but overall, it should incentivize donations from everyone.
