Oh yeah, three things I thought were fairly significant departures from W:ET:
1) Engineers don't plant dynamite anymore, soldiers do. Personally I don't like the change. Now engineers' only purpose is to construct things. It's weird because engineers are the ones that blow things up with heavy explosives in real life. Plus I think it's a bit unbalancing. Now a lone soldier can plant the explosives and camp the plant with a rocket launcher or heavy machine gun. Before, you were sort of at the mercy of your MP40 or Thomspon and you wouldn't be able to withstand more than a couple enemies.
2) Covert ops actually take on the weapons of the body they use. So you don't have your sniper rifle, you have whatever you picked up (but you get it back if you lose your uniform).
I still haven't figured out how you tell if someone is a covert ops. Before, you could tell by their skin (if it was an axis that stole a allied field ops uniform), their weapon, or their name flashing weirdly when you ran your cursor over them. So far as I can tell now, the only way to tell is to see if they are running in the wrong direction or have your name.
3) Once you are out of grenades, you're out until you die. Ammo packs don't refill your grenades.
