I was pro templar In DAO (i had recognized the value of the templar order, but some reforms were needed), i was pro-templar DAII and for good reasons, aside from meredith and some other morons, they were a n excellent order in Kirkwall, great Cullen.
DAI pro templar once again and even without hesitation the reasons are obvious.
Many are Pro-mages because mages are the figures that they wanted to be, a dream in the heads of many players, so is obvious that the Bioware had created the atmosphere to try to make the templars more attractive, since the mages no matter the disaster they would cause, they would have always a huge number of fans, due too their magic.
