What exactly is the point of controlling healing accessibility so tightly? The 4e healing surge mechanic seems more towards allowing non-clerics to boast that they too can heal on their own without having to rely on clerics, but I just find it irritating when the party defender runs out of surges after the 2nd or 3rd fight and the whole party has to stop, even though the controller still has all of his.
While many others felt differently, "Now in 4e you don't need a Cleric..."
"...he can be a Warlord! *ba-dum ching*" is exactly how that came across, especially since having a "Leader"-type was never particularly necessary in my 3e groups, whereas it sure is in 4e.
