I wish the sims team would let us have base game weddings while having MWS

Yes, same here. As well as the option to leave at the altar which I've read is also gone. Not that I'm sure I'll use it, but it's about having all of the options available. The pack is called "My Wedding StorieS" - plural - after all, so we should be able to use it to do exactly that, i.e. tell lots of different stories.
