+1 to this! If we're gonna be in EA for a year or more... those of us who genuinely want to be good playtesters probably need some better tools for bug reporting, collating data on feedback etc.
And some guidelines around what is in scope for changes, and what may not be due to technical constraints or irreversible design choices. So that we're not wasting everyone's time banging on about things that can't actually be changed for release.
