Making the STFs easier will not solve the problems that arise from random grouping, nor will it really have any impact on failure rates (Bad groups are bad groups). It will however make the STFs considerably less fun for those of us who find them to be a bit too easy already.
Elites shouldn't be pugged, hands down. If you choose to, expect to fail..at one point I know I did everytime I pushed that button. The flipside is there are plenty of other ways to run STFs without relying on the queue system.
But that's a great way to challenge yourself! If the STFs are too easy, go try PUG with elite cure space. There's your challenge, superman.
