FYI: the plan is to merge HCS and TA at some point, likely after the sandbox patch. The image below looks like he's talking about HCS and Ranked Slayer but the full context isn't there - he's absolutely talking about HCS & TA.
The HCS playlist was only ever a temporary thing until they actually started to work on the sandbox.
Why get rid of Skirmish?? How the hell are we supposed to warm up in a non-ranked playlist??
Nothing gets my shot on point like a good round of Infection.. I mean c'mon 343. Who is making decisions over there??
And merge HCS and Slayer?? HCS already is basically a slayer playlist. I get slayer 9/10 times.
