Inquisition seems pretty determined to make both sides of the Mage-Templar War look like utterly pathetic and weak-willed fools. I mean, almost all the Knight-Commanders and senior officers of the Templar Order decided that worshiping an ancient darkspawn magister was a great idea, so why can't Fiona do the same?
It's stupid of course, but since stupidity seems to be theme for this game it doesn't surprise.
True. I suppose it has to do with Alexius' and Lucius' plans succeeding, and for that the mages and templars have to lose.
The difference here is obvious. The templars were taking red lyrium. Corypheus spoke to them through the taint, as Cole confirms. So for the templars it was a simple matter of making that first choice to take red lyrium (or have it forced on them in some cases). As for the rest of the templars, they were following orders. Which is what you're supposed to do when you're a knight. You are supposed to be loyal, work as a whole, and keep your word. But you should also be able to question what you're doing when it's clear that it isn't right, and many templars were realizing this. The problem was that a fish rots from the head down, and likewise the templar order was corrupted from the top down. There was no way for the lower ranks to change things, except by embracing the Inquisition, which it can and does do if the Inquisition shows up asking for their help. But even then, red templars are said to be stronger and more powerful than normal. So even then it was an uphill battle.
With Fiona however, she was the one leading, but she just didn't know how to respond to the situations she faced. She could lead the mages to freedom, but she didn't know how to survive with it. She didn't know how to handle outside forces. But for the charity of others, the mage rebellion would have fizzled out soon after it started. Most of the rebel mages did not want to go to Tevinter, and some even wanted to go back to the Circles. So yes, the mages' problems were mostly due to Fiona and her incompetence. But this extends only so far. Fiona's crime is not knowing how to respond to most problems. That doesn't mean she doesn't know how to respond to all problems. If Alexius betrays her, she responds by turning on him. We see this happen in the mages path. I am willing to bet that her seeing a darkspawn lead the Venatori would also be a problem she would respond to correctly, by refusing to serve the blight. Makes sense in context of her history as a Grey Warden.
So this is all about seeing the story in context. Yes, Fiona was stupid. But that doesn't make her stupid on every single issue. When it came to protecting her people, her heart was in the right place. So logically she would be consistent with this. She wasn't in Haven, which means there must be something more to the story. Blood magic is the most likely explanation, and it's the simplest.
Now, if a short story is written to where Fiona is shown to actually be a cold-hearted murderous scumbag, fine. I'll accept that explanation. I hate Fiona anyway. I delighted in her getting frozen and shattered in Haven. I took screenshots of it.
All I'm saying is, be fair. Only blame Fiona for the things that definitely are her fault, and in cases where her actions contradict her previous actions or statements, be aware that there may be more taking place behind the scenes that we didn't get to see.
