I like most of the changes in the U3 beta, I absolutely hate the powerplays(well mostly the double damage/other team can see you)
I actually like the boosters Cloaked(so campers won't notice you as much) and back in the saddle(works well for 2vs2vs2...but i understand why it's unfair)
I disagree with the maps making the matches slow-paced, every match(team deathmatch/hardcore/free-for-all/) I have played have been an absolute fire-fight.
I thought a good portion of the Uncharted community wanted a free-for-all and its well implemented
kickbacks work well and some require a good amount of medals to activate, but the lower ones can be abused(speacially those treasure chest "3 medal pick-ups)
I think ND solved most of ones dislike as the could just play hardcore mode
