Players nova its happened in every edition to some extent. It happens in 4E too and the reason it wasn't a problem last night in our 4E game? We knew we were up against a deadline otherwise our 4E party probably would have strongly considered resting after one fight. Not to mention that on at least 4 seperate occasions the DM was so bothered by our group blowing dalies on the fight that he kept mentioning how "it must be nice that you guys know you won't need those dalies in the fights to come". Suggesting on some level that we should not have been going nova. So try as some folks might to present 4E as the edition which "fixed" this "issue" it always been up to the DM to fix not the system, and that has remained the solution regardless of edition including the current iteration despite claims to the contrary.
So novas are a problem if you allow them to be as the DM seems very true to me. That the solution is AEDU just makes me laugh.
Our group's situation in 4th edition also proved problematic. Because we are all responsible adults with children, blah, blah, blah, our game time was rather short. After socializing and snacking we had maybe two hours of real game time. Our DM actually encouraged us to expend our dailies because there were some survival issues we had as a group and because one combat was all we were going to get in a session anyway since 4e combat lasted forever for our group. It really became quite boring. Why players want to blow all their powers if they don't have to is beyond me.
