REQ system broken?

This has to be an issue… I can’t honestly believe the game was designed like this. I’m level 52 I’ve been playing for months on end. I’ve purchased all my Bronze packs till it told me I’ve unlocked the all the common perm REQ cards. I’ve now been buying Silver packs and occasionally a few gold packs.

At level 52 I have yet to unlock the DMR, a base loadout weapon in the game. I have all of the weapon skins unlocked for the DMR aside from the ones you can only get from pre-ordering. Weapons skins for gun I can’t even use. This puts me at a slight disadvantage when playing Warzone, as level 6 REQs come along a lot of maps turn into long ranged battles. Unless I find one on the ground, I’m target practice.

I was told if I was having trouble receiving some of the important unlocks for Warzone, I should pick up the Warzone REQ Pack bundle. Like a fool, I did. I neared my final Warzone packs and still no DMR. I have most weapon mods for BR, AR and SMG… aside ultra rares and legendary ones cause I’ve been sticking to Silver packs. I see a ton of different loadouts for my AR, BR and SMG. But I look at my DMR loadout and it’s empty.

What can I do to unlock this damn weapon? I’ve tried nearly everything. I have never played an online FPS that has forced me to go without BASE weapons for a game, for this long! I’m not asking for the legendary H2 BR or some Mystic weapon. I’m just looking to get a normal weapon loadout. What’s the drop rate for this thing?
