Honestly I don't mind what they do. I will be happy either way, just as long as the online multiplayer is good then I'm happy.
I like being able to create and have a personal emblem made by yourself.. But I don't like seeing massive d**k emblems, because once my mum walked it in I was looking at every person's emblem who was in my lobby and guess what... Someone had a massive c**k emblem squirting sperm and my mum turned round.. So awkward lol
I also do like the preset emblems too. But really they could do something completely new and different, you don't know. Anyway treyarch.. Surprise me.
