I’ve been playing a lot, and I still haven’t unlocked the Sniper Rifle in Warzone. It’s pretty ridiculous that you rarely get anything that matters in packs, and he only ones you get anything in are Gold packs. Even then, I get like one uncommon helmet, and uncommon armor/visor, and then a bunch of cards I already have, and won’t ever use.
The reward packs for leveling need to have a little bit more value. I get that they want you to buy packs with real money, but with the amount of cards there are, you should be getting them at a little faster of a rate. Not to mention playing Arena is essentially pointless, since you get barely any Req points from it.
