I post in the voice of Christopher Walken
I thanked God for roles in the Fourth Edition. It made explicit the needs of the party.
I am playing Pathfinder now and our party cleric has decided to change his channeling into negative damage energy and to concentrate his spells on commanding undead. So now we have no buffs and few heals. And his evil ways mean I feel unable to play a Paladin or Good Cleric. Because he is "creating a character out of an image in his head" rather than worrying about what is necessary. (I wish we could just leave him at the dungeon entrance. Heh.) At least a Fourth Edition leader can always heal at range with a minor action a couple of times per encounter regardless of his feats and powers.
The thing is, some of us want the option to include the non buff, few heal cleric in a party. In pathfinder you have the option at least to it either way. For some groups parties like this wont work, for others they will. A lot of it comes to the style of your game.
