1) Once again we simply disagree, based on the evidence in Inquisition of how The Imperial thrones favor can sway the election of a divine I'd say the chantry is certainly under the heel of Orlais
The Imperial throne has nothing to do with the election. The Inquisition's support of a candidate is an appeal to the grand clerics, not the nobility, as is stated multiple times in the game.
2) The sucession of the divine works how the nobles of Orlais say it works,
Again, you're just making up stuff as you go. I'm not going to debate your fanon.
This is clearly stated in the game, by Josephine, Vivienne, Leliana and the Inquisitor themself.
It's not.
3) In Gaspard's situation he is the Emperor of Orlais, If his favor can sway the nobles to such a degree as to get A mage divine elected by the Inquisitor,
You keep wanting the scenario to be like this, but it's not.
5) True, though Celenes doing nothing about Halamshiral only to eventually be lured into street combat there personally with a small force because she thought she was loosing some favor from the court proved she herself is terrible at it. Then there was her abandoning her plans for Ferelden solely because Cailan was married. Then returning the tomb of Koslun to the Qunari because...why again did she do that? She gained nothing except to boost their morale come the next invasion.
So you can see why my first choice wouldn't be a person who sets the bar even lower, right :>
6) Last flight we only saw the few grey warden mages, not how mages were deployed tactically,
It was a war, they were all deployments you doof.
Fifth blight we only saw the initial charge and nothing else of the battle of denerim, apart from the Grey Warden summoning a small group of mages that broke away from the battle for him and this I would imagine is only gameplay mechanics (and it was only 15 anyway),
The mages departed for the battle in a single group, and fought as a group when summoned. You also forgot the battle of Ostagar, where they operated the exact same way.
But no, I'm sure most people would rather have the feared mages just randomly sprinkled about their army. Sure.
The Saarebas operate in units called Karataam.
You have Chevaliers to take care of them, better trained and trained in Templar techniques anyway.
Considering that even Michel, the most op Chevalier alive, gets ******-slapped by magic pretty consistently in TME, I don't really think their "Templar techniques" that don't actually involve any anti-magic really amount to much. lol gg
