I WOULD like to see more races and classes in EA though. They will need to be play tested before release as well, I think.
We have companions and player setups in the current EA that are based on the general game mechanics of physical attacks and spell casting. We're all testing various combinations of those abilities with our different party setups.
New classes we haven't seen yet, like Ranger, Bard, Druid or whatever, will be just variations on the fighter and spellcaster themes we're already using. Maybe they can be tested internally without dumping them into the EA.
