As a druid who's healed 5-man groups through all the (5-man) instances, not always with a paladin around to help, and with various mixed groups... not sure if I would agree that it forces your choice of party members. In a guild that never had a really good mix of classes, we made do with what we could. We never had a mage at high enough level until the past month or so (or warlock), and made do for aoe with hunter explosive traps, pally consecration, or just plain old "You stab them." Easier with the 'ideal' class selection? Sure. Impossible otherwise? Nope. More of a challenge, but that's where the fun comes in.
