People complain these days about the arena being empty. Waiting for a random battle is taking forever. I believe the problem is that most people already have all the CI's or are just not interested in the ones they don't have. That why the arena needs a refreshment: to draw people back into the aren, because they want to have good rewards.

They earn tokens by fighting and those tokens can be traded for CI's (atm). Why don't you add an extra reward system? ex.: you battle in the arena and win tokens, now you can trade these tokens for the CI's that are left, or you can trade them for mana/power/energy/gold/gems. You can make this a random box, if you choose it you'll get 1/5 chance for each of the rewards. The more tokens for the box, the more you'll get out of it.

ex: box = 15, 30, 45, ... or 300 tokens

box15: 15 power or 15 mana or 1000 gold or 2 topaz or 30 energy
box300: 400 power or 4000 mana or 22000 gold or 700 energy or gems
---> gems in box300 are: 40-80 topaz, 10-20 sapphire, 3-5 ruby, 1-3 jade, 1 moonstone, 1 emerald, 1 diamond (that means you have 1/5 to have gems, and 1/61 to have a diamond - 0.003%)

You can buy boxes whenever you want ofc, and I think more people will battle in the arena when they have something to battle for.
