Yea that's all true, but there's two ways to look at it, yours and mine. You will quickly learn that people will log in and leave upon official release because of the economy already having a shit load of items in it. It's happened to almost every server that didn't reset beta accounts, prior to release. I know you don't think it's a good idea, and some beta users will be upset, but it will reward you in the end. Obviously it's your choice. As to why people would join existing servers that already have an economy, well no one really stays on servers with low players but an economy already set, they usually leave but players will stay if your server succeeds and has say 500+ online like Alora, stating back to my reset suggestion and you not resetting, this most likely wont have hundreds of players
. It's just how RSPS' are nowadays, people expect a new server with an official full release, to have a fresh economy and a competition to get the first items, 99's, max, etc.
I wish yea luck.
