I don't know if I really want to see a bloodied, beaten Leliana. I think it's implied by her "No one should have this power" comment that she was tortured using magic, anyhow, but there's also the dialogue right after the scene where Dorian tries to talk to her about it.
Dorian: What happened while we were away?
Leliana: Stop talking.
Dorian: I'm just asking for information.
Leliana: No, you're talking to fill silence. Nothing happened that you want to hear.
That right there is shiver inducing enough for me.
DA does have a mature rating, but it isn't Game of Thrones. I think a suspension of disbelief is important when playing any video game. Maybe if she looked a bit more ruffled or wasn't wearing lip gloss (though perhaps being able to apply gloss when bound is another one of her many valuable skills). Maybe if she had a cut on her lip? I don't know.
Other than that, I personally have none of the same issues that you have and I hope you won't take offense if I say I find them just a little nit-picky. 
Offended ? Nah. This is an online discussion. Getting offended over this is pointless. You would have to resort to extremes to get me offended. I'm like Sten in that sense. For the most part stoic and indifferent.
Just interested in people's opinions really. 
My personal viewpoint of the mature rating is that it means treating the gamer as an adult and as such should not censor anything and just go all out. So when I see torture scene like that in a game like this, to me, the game is not treating me as an adult and is instead treating me like a child who should not see blood, gore, trauma.
Then again, maybe Game of Thrones did spoil me. I love the books and the series. 
As for the dragons and wild animals, I stated that those are suggestions as opposed to actual critiques, my critique being focused on Leliana and fetch quest.
I have lived nearby a forest so being around wild animals is not something new to me. Animals tend to act a certain way and you can typically drive them off.
I suggested driving them away as an option because perhaps you might roleplay as a Dalish or a pacifist or someone who does not like to waste things. So perhaps driving animals away or calming them down, especially as a Dalish, being closer to nature and all that, it seems to be a better path to take. You don't have to just get XP from killing something blindly.
I am very big on roleplaying and realism in an RPG game. When I play one, I tend to make a decision based on what I personally would do if I was there faced in that situation.
So unless I need hide for crafting or meat for cooking, in RPG games I would just sneak past or calm the wild animals and move on. I am weird like that.
I was also wondering why dragons are enemies in Thedas. In other games, dragon are enemies because they want to bring an end to the world (Skyrim) or something like that. Just wondering if there are more reasons to attack dragons in this game other than "good loot". If not, my Inquisitor might not just bother them if they are in the wilds roosting and chilling.
