Zeriyah:
With the Arena reward restructuring, we pretty much just took the rewards that you would normally get in Arena mode and put them into fewer boxes. So, for example, instead of opening five boxes and getting a pack and four boxes full of 5 Arcane Dust each if you didn't have a great Arena run, you'd get a Pack and a box full of 20 Dust.
The rewards should also now clearly be better the higher up in wins that you obtain. So there shouldn't be a reason to quit out at 8 wins, as an example, and it should drive you to strive for the 12 wins and the best Arena loot possible.
We're not trying to hide anything - our intent is quite the opposite. Win more, get more.
