Lost free changes for Plats on Awards. Biggest one for me.
Also now we have a watered-down, almost worthless, EEPs.
Increases in miles required for awards.
Difficult or impossible to book DL awards ex-anywhere except USA.
I think we're going to lose MH awards using miles. (?) Unless DL is their partner.
Ability to upgrade on KLM after this year using NW miles? I assume that will be gone too.
Lost 125% bonus for Plat
Moving toward the obviously inferior web site (DL) instead of NW's. How can this possibly be explained??? Even an idiot can see they must have decided for stupid reasons.

Gained:
SQ awards on DL
Wow, this is tough......
