DLC/Update Achievements

If you have been with the Halo series, you know most DLCs come with achievements as well. I think Halo 5 needs to include a handful of achievements pre update that goes with the theme. So example for the next update:
-Infect 5 people in one match
-Wearing Emile’s armor, shotgun 15 zombies in one match

Or for past updates too!
-Earn a Killtacular in Grifball
-On Skirmish on Darkstar, kill or assist in killing Lord Viratus with a Mantis.

You get the idea, I know this is more work for the updates but it’s another way to enjoy each update! What does everyone else think? Got a idea for achievement?

Iv got all the achievements for Halo 5 and they dont really feel like youve done a lot so this would be nice.

I read somewhere that only paid DLC brings achievements with it. Don’t know if that’s a hard-and-fast rule, but it seems to be the case with Halo 5 at least.
