Depending on encounter designs... and thinking about some existing encounters without the non-healing classes...
Warriors - Itemization aside, there's not a whole lot that couldn't be tanked effectively, though not necessarily as efficiently, by say a well-geared tank specced druid in the game as it stands right now. Who knows if Blizzard will put in certain encounters that take require certain warrior skills though.
Rogues - Poison effects were mentioned by someone. And certain encounters in the game right now do take advantage of rogue stuns, which could well continue into BC. Though you have the pally ranged stun for both sides now. Lack of Disarm Trap would make the Broodlord trip rather difficult. Also thinking of Razuvious, where we use evasion on the pull (or hunter deterrence, but usually a rogue)...
Hunters - Tranq shot. Blizzard seems to stick that one all over the place. Anub'rekan without Aspect of the Pack? Not sure how well that would work.
Warlocks - Banish was mentioned. Whether or not that'll make encounters impossible... depends again on encounter design. Curse of Tongues if that continues to be a factor. Long-duration fear perhaps as well to keep certain mobs out of commission. Lack of a summon won't break the game, but does create a lot of inconvenience if you have to replace someone and you have an hour or two of respawn clearing behind you, if a dungeon is so designed.
Mages - Frost nova is quite useful in a number of places, where you just have to have the mobs stuck in place. Lack of sheep you may be able to deal with, depending on encounter... eg. stunlock/fear the mind controlled player, or whatnot. You lose the frost and fire damage, which may be an issue if encounters are designed with those particular vulnerabilities in mind.
Some encounters will be doable, and I think some would not be, depending on the skillset that is required for each encounter, and whether there are alternate ways of doing it. I can't say I've looked at BC encounters in detail, but given Blizzard's past encounter design, I would not be surprised at there being requirements for all the various class skills in some form or another.
