ME3 is my only game of March but I'm not even sure I will get the plat before DMC HD collection comes out...
After close to two weeks I still have only played 8-9 hours in the campaign...
And 5 millions co-op hours.... So addicting, and I still don't have most of the weapons I want ( gimme a Black Widow and a Paladin and gimme piercing mod for sniper riffles..)..
Have only beat 3 gold maps too, few people want to play gold these days , especially since the patch made Geth Gold missions harder... So I spend my time playing Bronze from lvl 1 to 15 and then silver from 15 to 20..
Silver is challenging , Bronze is a little too easy although most of the Bronze games are with low levels so they can still be challenging, especially when people quit in the middle of the game..
I played a bunch of Gold Cerberus last night with friends but we never made it past wave 8. It's doable but we were trying it on harder maps.. Still starting wave 6 you get so many phantoms attacking you pretty much need someone with stasis to have a chance... As for Reavers Gold, I have never tried it nor found anyone crazy enough to want to do it.. ( I guess if everyone had high rocket count it would be doable...)
Although as people get more of the rare weapons and start getting upgrades for those things will become easier..
