I know there is not enough turbine/DDO staff to thoroughly test for you, so here is a suggestion...
Offer us, your members a chance to win turbine points, rare named item, recognition or something for playing on Lammania test server for being the first to find bugs/issues.
I'll bet this approach would get more test players to test out and find more bugs/issues before you launch a product that isn't ready for market
Just a thought/suggestion
