Hazard zone "8 to start" too high a bar.
Trying to get even 8 players to start a Hazard Zone game is too high of a hurdle to cross. Let's be honest, all the other games can be played with AI why not this one? 4 players to start is an achievable goal and your lone squad vs AI would be ok. Trying to get 8 players is a monumental task on Xbox one.
Part of the reason nobody plays or even tries to play is because you can't. One will sit in limbo on the lobby as players check in wait for a time and split, counts go from 3,4,6,7,5,6,4,3,2, and then you quit after 15 minutes for nothing.
You don't have it on portal so you can see player counts before you try, after you do try on the HZ tab it just feels like time you'll never get back.
EA doesn't even feature it as a limited time mode to encourage people to try it. Either support it properly or delete it and it's achievements as trying to complete the missions and achievements is like trying to run up a waterfall.
The way it is set up currently the bit of fun you could have playing it isn't worth the hours it takes repeatedly choosing it only to get one game every few weeks.
Change the "required to start" count to 4 and the server might even reach room temperature from use.
