This is what 343 is trying to avoid.
A bothbothbothboth smattering of shitty hoppers does not a good game make. I've spent enough of my Halo career wishing I could play Multi Flag CTF only to be stuck in "Team Objective" or "Team Skirmish" and cursing the day we got matchmaking. I'm glad they're trying to distill the game down to its best offerings. They may be faltering in some of their choices of the "best", but I disagree that Regicide is an example of that. It's a focused FFA gametype, something that FFA has always needed.
I understand what you're saying, but for FFA i think they should have both. When the game comes down to who ever can get the most +35 pts off the king, the luck factor reminds me a bit of Headhunter. I think regicide is cool, I'd just like another FFA game type.
