No multivariate testing and have to use 2 different pages now. Really miss GWO, very easy multi-variate testing, simple, FREE. Not real time was the only downside.

You can have Experiments running on client side (JS) without redirect to different versions of the page, but setup process is... strange to say the least - https://developers.google.com/analytics/solutions/experiment...

Still, after setting it up it worked just fine for us.

Also, I have yet to figure out how to run multiple experiments on the same page (rather than multivariate single experiments). Usually frowned on, but when you're testing a new search box site-wide and different CTA buttons, they're discrete tests.
