What is lacking with having only dedicated servers is the progression of your multiplayer profile unless you are playing a mod or something. That's where matchmaking could potentially be better. It opens up for a competitive ranking system much better. I liked c-RPG in that it gave means to grind game after game (leveling progression). But as of now, leveling serves no purpose and there is no "higher cause" for grinding. I don't get "just one more game" urge.
Without something to aim for (be it profile level, badges, ranking, unlock skins), it is way too casual and matchmaking serves no purpose really. Then you could simply have dedicated servers you could casually hop into for a game or two like in Warband native.
I really hope they expand on a ranked or a similar competitive focused system where you effort and performance gets noticed. That's the only reason you have matchmaking.
