Now this is what I'm looking forward to.
For me pretty much all of Halo 5 has been a huge disappointment. The campaign is lame, forge doesn't interest me, and the multiplayer has promise but ultimately competitive multiplayer interests me less these days.
Warzone seemed promising but when I tried to get into it I realized I had no good req's unlocked and everyone has fancy weapons that just destroy...so it wasn't too fun. But with Warzone Firefight I can unlock those req's and use them in competitive Warzone to give me a fighting chance.
