I dunno.
May give it a go this weekend, what with the event going on and all.
I don't have a lot of free time, so I'm in the habit of scrutinising everything to cherry pick what I waste my few free hours on.
As always, I'm probably just over thinking things, lol.
Unless all 4 players are complete newcomers(which is like...impossible), its rare to lose a Bronze match. You usually get some guy with a high N7 rating(and good overall experience) and some OP gun they got from a spectre pack where they could basically carry the whole group. Hell, that's what i do sometimes with my Krogan Sentinel lvl 20. I run all over the place killing every geths/cerberus/reapers in one melee hit without dying.
And I never see anyone get kicked while waiting in a Bronze lobby. I've seen it once or twice in a silver or gold one, but that was because the guys were lvl 3 or 4.
You can get from lvl 1 to 6 or 7 with one completed bronze match too.
