I'm starting to wonder if WotC will eventually just edit the cleric out of the core books.
The original concept of cleric was a healer. But WotC realized that not many people want to be healers, so they decided to give the cleric a notable power boost above other classes to make it attractive. Medium BAB, full casting, two good saves, etc. Then, with general power creep going on in the Complete Divine and Spell Compendium, clerics got buffed up even more. Now, it's to the point that cleric spells and rounds are so valuable that clerics never want to waste them on something as trivial as healing, so we now have the infinite healing items in the MIC (and Eberron, IIRC), and apparently an infinite healing feat as well.
With all of these infinite healing methods, it seems that constant healing is pretty much expected to be the norm, now. To cut down on the paperwork, lets just rule that all characters are healed back up to full HP at the end of an encounter. Then we can just rename the Cleric the Divine Powergamer and be done with all of this healing nonsense altogether.
