I voted to keep as it is now but I didnt know staff was working on a new server.
So my vote now is yes, reduce the amount.
There will be no point on keep this if many ppl will leave for the new sv.
As shadow already said, the new server is not like SG so they arent in competition to each other. That fact shouldn't influence your choice here atall but eitherway, reducing the amount of soulstones is a completely contraproducitve thing to do as it will just hurt all the beginners.
Realising that the vote is literally 50-50, that means its not only bad for beginners but also not as liked by the existing playerbase to justify such a change.
