One of my absolute favorite things is the way they made Scouts (freaking awesome class) and put in Marksman Rifles (bolt-actions that can get an attachment to grant Squad Sight) so you can have a more mobile flanking Sniper-type if you want. I love that there are more valuable options for gunners as well as making Rocketeers very, very valuable as they now have assault rifles for normal attacks as well as their rocket. Not to mention the crazy-as-fuck changes to the MEC class.
