I like it when I get to hear "Game Over". Thats always awesome.
Seriously though, there are certainly things I enjoy, its just that there's so much crap which ruins it. I think MLG cuts away a lot of the crap so to speak, but I dont play it lol.
I don't mind assassinations that much, im just surprised they bothered even bringing them back, again, they are just fluff. They seem to appeal to the dudebro's who just enjoy pre-scripted head stomp style kills. They can disrupt the flow a little. I just think it was more satisfying to backsmack and watch the ragdoll spin while shooting the next guy. I just hope Assassinations aren't indicative of other design decisions.
