Go play the novice player NPC's with the main goal of getting all the patrons pointing towards you. I had countless games that only lasted 2 minutes. That's 45 guaranteed experience each match.
~This grinding method can work with proficient NPC's as well, however; they use the patrons on occasion, so it gets irritating. The expert player NPC's seem to know when you're about to achieve a patron win and they will try to prevent it, which is even more annoying. I recommend simply shredding through the novice NPC's over and over again. It was the fastest way for me. Always do the female khajiit's quest each day and the redguard's quests when available.
~I really wanted the red eagle deck. It requires rank 7 to get and that's why I did this.
~Simply playing Tales of Tribute so much will still help your game.
I hope this helps!
