The Templar, the only way is to grind unfortunately, but as you know when the medallions stack, you gain rep once you get a win, but this will certainly add up more as IB comes to a close. Wear the emblem, shader, and class item as they will help you too. Turn in your gold (weekly bounties) on Monday depending upon where your rank is at and most of the time I end up with one or two gold bounties in store for the next IB. I hope this somewhat helps.
