Is BSN biased against black characters?

Hell yeah

Well as defender of 2/3 of these characters here's my 2 cents. Jacob was doomed after he was reintroduced in ME3, personally I thought he seemed like he was forcing most of his lines and seem overtly chipper compared to the by the books guy I met in ME2

As for Vivienne, she pro-circle and pro-chantry this people view her with hate because every about the Chantry and Circle is "evil" apparently. I personally agree with her views when it comes to the Circle, I certainly don't think it she be utterly destroyed like most people, change certainly but not destroyed

Now for Liam, alot the hate from I've seen stems from his Nomad convos with Vetra. I personally never heard them before looking them up. Personally I think he's funny and upfront when he needs to be. Some people see this as rude but I don't, he does always apologize when he goes to far

Now does this make BSN bias against black characters....Nope, Bias against Human characters...MOST DEFINITELY

Go back to Tumblr, OP.

Obv it'd be better if all the squadmates were interesting, I was just (somewhat jokingly) questioning if simply being boring marks a char as badly written.

I think I see where you are coming from. Example - Holden Caulfield (Catcher in the Rye).  Great character, well-written.  Boring as hell (by design, both boring and bored with world). 

Would chuck him outta an airlock if he tried to set one boring-ass angst-ridden foot on my ship. 

Traynor's not black.

She's Anglo-Indian I believe.

I never hated Jacob in the original series and one of my most favorite characters is Captain Anderson, I really wish I could of had him in my crew..  I even liked Liam in MEA up until his Loyalty mission.

I am not sure where you are getting the idea that they were hated.

I liked Jacob in Mass Effect 2, it nice to have a squadmate who confident and stable for a change. Jacob in ME3 on the other hand...

For all the talk of "Daddy Issues" in Jacob's Loyalty Mission however, I'm surprised how no one brings up that Ronald Taylor pretty much being one huge Heart of Darkness shout out. Being marooned on a deserted jungle planet where pragmatism devolves into brutality and delusions of godhood, with imprisonment or death being the only escape. Hell, you could also match Ronald's fall thematically with the Reapers, with the toxic food subbing for indoctrination.

Jacob got balls of steel. How many people gets to dump commander Shepard for someone else and live to talk about it.

I'm chalking this up to unfortunate coincidence.

really? I got the impression that he is anything but chill. The character establishing moment for him was him emptying a clip into a dead Kett. that's a bad way of establishing someone's chillness
