My apologies ahead if this will sound rude, but I mean it as a genuine question: "Did you wanted role-play reasons to go to templars or just an opportunity to argue why going to mages is better?"
If you read the thread, you'll see that I've acknowledged several times when someone presented a good idea that might work - although none seem to be quite up to the task of overcoming the urgency of the threat at Redcliffe, some do get close enough that I was - as I have stated - able to go on and go after the templars, with a little head-cannon action.
So to your question I answer, yes, I did actually, really, honestly post here looking for a GOOD line of reasoning that would allow me to go after the templars after finding out the threat at Redcliffe. That I don't accept every suggestion as sufficient to the task, does not mean that I categorically deny that good suggestions aren't possible. In fact, I found a few here, and this thread helped me do what I wanted to do: go the templar route even after having gone to Redcliffe and seen the threat there.
To quote myself from an earlier post:
"The way I did it in the end was just to head-cannon it so that my Inquisitor was inexperienced with magic, and didn't trust her ability to deal with the situation, and going to the templars for help was a desperation move; one that backfired as she now discovered she cannot immediately go after Alexius with the templars after all. So she considers her actions to have been a mistake - and after seeing the templars fooled by a demon, she doesn't trust the templars enough to lead themselves, and subsumed the order into the Inquisition. But as she told Solas later, beggars can't be choosers, and she just has to make do with the situation as it is, and hope that Alexius isn't about to freeze all their asses.
It still felt a bit weak to me, but it'll do, I guess. "
In fact, I don't argue at all that going to the mages is better than going to the templars. What I argue is that once you know the threat at Redcliffe, going to the templars BEFORE dealing with the situation there seems hard to justify.
