I like REQ packs. The randomness of what the other person is gonna have from cards keeps warzone fresh and admittedly SLIGHTLY unbalanced but nothing that breaks warzone or stops skill.
I like REQ packs for at least the unlockable armor. It is a lot like ME3. As for the weapons and bonuses and stuff? I could take it or leave it.
Although it does mean I’m never failing to get a tank to an ally when I can spawn my own. So that’s a plus.
