DC needs to be that expensive?

So i was talking to some people ingame, and turns out 1 U$ = 1 DC. I went to check what i could buy with 50U$, and the options are really low.
I could get a frozen kylin set, with no DC leftover for forging. Maybe 2 goddess ring, but nothing interesting to buy with the 14 DC left. And other not so good options.

I believe 50U$ for a private server, is a really high "donation" for a casual player, and should give the players way more benefits than what it gives now.
The DC price in my opnion right now, is a real "turn off" for any potential donator. If you could trown 20 bucks and get a real improvement in your character, then maybe you can donate more times, even if its a low amount, but "having" to donate 100 to 200 bucks, to be able to buy the most expensive items, makes the server have a low donator population, wich means people that can't donate, will never get donator items, because its not worth it to sell DC for ingame gold, since DC is so expensive.

My sugestion would be, to make the donation worth at least twice as much. 36 bucks for a pair of goddess ring? make it 18 for a pair. 50 bucks a kylin set? make it 25. And so on.
Maybe keep the high level forging cards expensive, so only the hardcore donators / players will get there.
It is a private server afterall, more players we have, better it gets, and if more people can sell DC for ingame gold, both sides wins, donator won't have to spend hours and hours farming, and non donators will have a chance to be as strong as donators. And of course, the server makes more money for other improvements.

We cant change rates now
I was a diverse rate in old bso and it didnt go well

Thats too bad then... i really feel like DC items are too expensive. I got some spare money and i would love to get 2 god. rings, but after getting them, nothing else is interesting enough.
