Hello,
I might would switch to EUW if I get the same money back which I can use on the EUW-Server or let´s say not money but the same Loot/Bountys which I got from my founders pack etc. And I think many would do the same. Because else (let´s say if some1 bought all 3 and even more) he invest 120+ Euro for nothing and start like a newby on a new server.
Since Server transfer not working maybe do this way and give those players their loot on new server. So people would actually switch. Even me with 1.1k iLvL (even if it hurts) but atleast I get my Loot from the money which I invest.
