MP is extremely buggy after the latest server-side changes (PC)

Just had a DX11 crash error message after only 2 waves using the new Human Artificer character. Her frost animations weren't showing half of the time either. It's clear that this stuff never went through QA and now its breaking the game.

We need a patch. I don't give a hoot about DLC's anymore, I just want the current MP to actually work. Here's a list of shit that's broken that i haven't mentioned above.

1) Cryo ammo armor debuffs not applying.
2) Incendiary ammo armor debuffs not applying.
3) Destroyers getting stuck while trying to rotate and target players.
4) Hydras firing missiles out of their asses (they don't turn to face you before locking on and opening fire).
5) RNG on weapons drops is F'd in the A (I have Uncommons and UR's left to unlock and got ZERO weapons, only ammos, after opening a Jumbo Premium Pack).
6) All enemies seem to give players a 90% weapons damage debuff by simply being in motion (running/walking).
7) Wraiths will immediately respawn directly out of a corpse of another Wraith that you just killed.
8) Matchmaker/game finder algorithm isn't working correctly. I can be sitting 20 mins in a lobby that i created and nobody joins. So i come out, hit quicksearch for the same difficulty level and immediately i find someone else's lobby.
9) Sticky grenade targetting hasn't worked since 1.09 went live. In 1.08 and previous patches, sticky grenades used to magnetize on to the target you were throwing them towards. Now they just miss and on some occasions, pass directly through solid enemies (even when you're playing as host).
10) Off-host headshots register as body shots when sniping.
11) Firebase Aqua (Day Time Version) has a graphical glitch that causes the metal floor at the LZ circle to flicker.
12) Receiver mods don't work with Silesh pistol.

MP is buggy as hell and EA needs to fix it. I don't care if they have to draft in some 3rd party devs or borrow some from Bioware Edmonton, we paid good money for this game and i for one expect it to work. 

Sure Bioware/EA isn't obliged to release any SP DLC, that's up to them. But they surely can't be allowed to leave a game this broken and refuse to make bug fixing patches for it after we paid top dollar.
