If you ever followed case studies for games with cash shops you would find out that only about 5-7% of your playerbase will make purchases.
Your donators would get pretty pissed when they end up on a server with very few players on it after donating.
My server had about 150 active players and generated 1200-1500 monthly and all of our donations came from the same 10-15 players.
