may I add my 2 cents to this? I was just thinking of a couple different reward systems the other day.
1. A reward system similar to the Achievement Points rewards,
Every 500 ranks gets you something like idk; 10 gold, a bronze chest (with t4 mats, and other goodies),+1% to gold, or +1% to magic find, +1% karma, +1% wxp, +1% skirmish tickets.
Every 2500 ranks gets you: 20 gold, a silver chest (with mystic coins and t5 mats?), +1 material from gathering nodes, 1 25-slot bag.
Every 5000 ranks gets you: 50 gold, a golden chest (with mystic coins and t6 mats?), 400 gems, 1 32-slot bag, a title, +1 extra Pip, 1 ascended weapon/armor box.
Every 10000 ranks gets you: a diamond chest (with mystic coins, mystic clovers t6 mats), 100 gold, 800 gems, a legendary of your choice.
2. Rewards for winning a match.
Winner Diamond Chest (you know the one you get from pips), . 10 gold. 20 reward track potions.
2nd Place Mithril Chest, 10 gold, 17 reward track potions.
3rd Place Platinum Chest, 10 gold, 15 reward track potions.
