Back when the realm had 2k, then 1.5k or even 1k population I wouldn't have thought about donating over $100 dollars.
But at this point...is it really worth it? with the uncertainty of the realm's future, nobody knows what will happen and as far as I know, it could be closed tomorrow if Kaer Wolf just wishes to.
Your might argue that donations is what keeps Neltharion alive, but that's not entirely true. Part of it it's the will of the players still willing to stay. And it's not going to be long before the realm turns like Warsong.
I don't really understand the purpose of this thread. Are you sincerely asking should u spend the money or is it another thread attempting to mock the realm?
