Other than sheer luck, you have to run the dragon quite a few times to get the SoS (or helm, or any specific desired loot) anyway. So why not say, "If you want a guaranteed piece of loot, you gotta run it 20 times for 20 tokens" or something along those lines. Otherwise, you get a 16% chance, right here right now
I think I could get on board with that!
Perhaps make the odds even with difficulty too? For example, 1 in 6 for Normal, 1 in 4 for Hard and 1 in 2 for Elite? Those numbers are arbitrary, but you get my meaning
