So since we can trade between our own accounts, I feel like the currency not included, should be tradable between accounts, (aka, Arena Tokens + piety) For Arena tokens, It would mean that you can distribute your tokens hourly enough that if one account has had a poor time and runs out, but the other still has plenty, that you can continue to compete dually. I don't see any downside to it, except perhaps that the arena bar may move a little quicker with there being more battles.

With piety, I can see one downside, that being that you can grind piety for stats on one account with a frozen king on the other, and then hit him up with the stats at the end of the month (which is exactly what I'd do, personally). however this wouldn't affect piety markings as lions can be transferred no probs. (don't remember any other uses for piety, sorry!)

I don't know, remember any other currency that isn't included in the present settings, but I'd really like to hear other opinions. I didn't find another board for this, so I made my own. Sorry if this belongs in "Existing Feature Adjustment" over the "Event Adjustments", I'll move it if it belongs elsewhere.
