Just managed to beat Gold against the Geth twice in a row pretty handily with a random team. Didn't even have a Quarian Infiltrator (Sabotage vs Geth = fun), was myself as an Engineer, two Soldiers and a Vanguard/Infiltrator, all Human. Hell, I think the Vanguard DCed or lagged out halfway through, and we still did fine. It feels like Geth really need another unit, an equivalent to the Phantom or Banshee, something you need to get away from and deal with immediately. Primes and Pyros are pretty slow, and while they have a lot of health, they don't feel as dangerous as a Phantom or Turret. If you can kill off the Primes/Pyros fast enough, you win...and they're are a lot less annoying to hit than Phantoms.
Picked up a fair few Spectre packs so far. Some interesting stuff in there. A Geth Rifle, Disciple, a couple rare unlocks (Krogan Sentinel should be pretty fun). Of note, I've actually picked up a Missile Launcher and a Medigel Capacity upgrade, so I can now use three of each per mission. I have no idea how many you can get, but one of the Soldiers I just ran with was rank 120 (The game just came out, jeez), and while I wasn't keeping count, he seemed to be standing up on his own quite a bit. The capacity upgrades were never the last item, so I don't think you'll get them instead of a rare unlock/gun, but rather as extras.
