I have an idea, there are many servers in very bad shape population wise and there's no real fix in sight at the moment since Blizz doesn't want to merge servers.
Before the trolls start with the "No Dalaran is teh ultimate suxors!!" I came from a Low pop server called Azshara and trust me you don't know the meaning of dead until you are on a server where Alliance doesn't down any content... at all. Do you like downing Nalak every week? Well my old server doesn't get to do that.
There is plenty of very sad players on these Low Pop servers.. I was lucky since I could afford the transfer. Many people cannot afford the $25 or more. Some are nervous to start over with nothing on a new server. Maybe we should go over to some of these low pop servers and encourage rerolls onto ours. Give them some bags, a couple pieces of crafted lowbie gear gear, a few coins in their pocket, and a friendly guild to call home and they might just stick around. Trust me guys, our server will be like a whole new game to these folks. Granted we won't be recruiting a ton of players with raid experience but over time they will learn like we did. Let me know what you guys think or share any ideas.
PS... please try to be positive. Being a "Negative Nancy" will not fix anything :-)
