"But some perks could be implemented like double xp perk which lasts a month or double drop rate? They still make you grind but you have an advantage over others because you donated."
I get where you are coming from, but on this topic I believe that's the worst thing a server can do. Specifically the double xp or even more so the double drop rate. Giving someone this type of advantage hurts the economy in the long run, I feel more than anything, simply because these items become less valuable. I get it's still a grind but it's not a grind everyone could choose to participate in, you limit it to those who have money to spend only. I believe this to be more a voting incentive than a donation incentive. I feel donations should be items that are obtainable in-game (easily) but also not overpowered. I havn't sat down to check the shop out yet but off the top of my head, I dislike shops that allow you to buy Elysians, Spectrals, and Arcanes. Those are very respectable drops from Corporeal beast and it ruins the fun of the grind in my opinion.
This is obviously just my thoughts and no one is forced to agree or what not, just thought hearing more sides to it may help developers determine better shop items or what not. Hope you all have a great day if you're reading this. :)
