The behaviour of always() is not what is expected. It get's fired every time, however if one of the promises passed does not resolve, none of the successful data is passed to the callback. Instead a workaround/duck punch of using .pipe() is required.

pipe() is serving its purpose here, however always should be getting the resolved values and the rejected values. This would allow for a semantic coding style of rejecting and resolving deferreds while giving developers to write a single function to deal with all the results.
