It is possible to get 18 commendations per day plus 3 commendations per week, bringing the time to get the mount down to about 11 days of luck and persistence.
First, make sure you are doing the Victory in Tol Barad quest each week. You don't have to be a PvP master to do this quest, just make sure your in the zone during the battle and (optionally, for the sake of your realmmates) assist however you can.
There are then a total of 18 daily quests for 1 token each that you can do. However, reaching all 18 will require you to cycle Tol Barad victories.
First, make sure you are doing the 6 dailies outside of the PvP zone. These will always be available and never change for a guaranteed 6 tokens per day.
Now, when your faction controls Tol Barad, there is three more quests available in the PvP zone guaranteed:
Each time Tol Barad resets, there will be a second NPC quest giver in the PvP zone who rotates available quests. There are 3 different sets of 3 quests, all involving the area outside of Baradin Hold. This guy will randomly cycle each victory you get, so it is pure luck.
So that is:
- 6 Commendations each day for quests in the PvE side of Tol Barad
- 3 Commendations in the PvP side of Tol Barad
- 3 sets of 3 Commendations randomly chosen in the PvP side of Tol Barad
18 commendations per day, plus 3 commendations per week.
(Side note: don't be afraid of the "PvP" side of Tol Barad, no actual PvP goes on when the battle isn't live, the opposite faction has no purpose to be there except for the occasional griefing).
