I think that whilst the ratio does matter (they can spin it however they like, but just 3 women in a party of 9 is very disappointing), I think its only as problematic for me, because I'm not impressed with any of the ones that *are* in the game. And don't anyone start on the whole unattractive thing - that's not what I mean at all. I just don't find any of the 3 characters leap out at me as being particularly interesting. And that's how I feel about most of the other characters too. To stay on topic though, my point is that if 1 or more of the characters did seem genuinely intriguing or promising, then it wouldn't feel so deflating. Because having just 1 character you really love is always better than having 50 characters you don't care about etc etc. But since none of the 3 interest me at first blush, that makes the fact that there so few seem all the more of a bad decision.
Cassandra for example, seems like an irritable yet determined woman, compared to the more easy going male lead (presumably Varric again). But it seems like Bioware are constantly using this archtype for their leading women (Bastila, Miranda, Morrigan, Aveline). I was kind of hoping for something different this time. Vivienne... well, Bioware don't have a great ttack record with ambitious female characters. Bastila was often panned for being a snooty so and so, Morrigan had a special mod created so people could slap her because she was so annoying to them (no, I don't use such things), Velanna is much criticised and is probably most people's least favorite character from Awakening, Miranda is also considered a bit of a pain by many etc etc.The idea of ambitious women who don't feel the to coddle or please those around them is fine, but Bioware's execution of that is frequently lacking IMO. Plus it means the romance is always 'thaw out the ice queen with your earnest and sincere love etc etc'.
We don't know for sure yet of course, but if these characters are much more interesting than they appear, then that suggests the initial reveals and intro pieces for the characters have failed. Because when you unveil characters, you should be trying to really sell them and engage people. Its just my opinion of course, but as this thread suggests, at least some other people agree. There aren't enough women in the party, and the ones we have seem rather underwhelming and overly familiar.
