So I was playing warzone assault with a few of my friends and when I was playing I had a very good idea for a REQ. Which was peaceable turrets. What I mean by that is placable plasm, chain, rocket, and the new placable guass turret. I got this idea from many other Halos(mostly Halo 2) when the grunts are carrying placable turrets into battle.
Now obviously you could rip off the turret and use it like the REQ weapons we already have.
It would be fun altough it mess with game balance.
