I'm curious, where is your proof that going cross server does shorten queue times?
I've seen no evidence that this is the case, from any MMO with cross server grouping. It doesn't even hold up logically that it would shorten queue times, especially not for DPS, which is the only group of people that needed shorter queue times.
Additionally, to me it's not even going cross server that is the major issue, it's the automation o group forming tools. I said it when the LFG tool first went live; I'd be happier with a well designed, cross server, manual group forming tool than with any form of automated tool, even if it were single server. Queue times of any length should not exist, because the game should not be forming groups for us.
