All I've been able to distinguish, thus far, are the playlist options. I appreciate that they are giving Hardcore players some additional support, allowing us to play gametypes that had been uniquely Core, but at the same time, it was nice to jump into a playlist knowing what I was going to play. Moshpit style isn't my favorite.
Can anyone confirm whether or not they've moved HC Headquarters into the "Bombs" playlist or whether they've removed it completely? Also, why add a "Bombs" playlist but leave Search and Destroy by itself?
