Refreshing without worrying about the cost is strategy. Have to let them know it will cost them to win. Is it not a partial win if it cost them 100 or more to earn 500? Especially if you have obvious collusion on a shard. Very hard to beat, so only other possible way to inflict damage is in the crystal yield.
Don't forget, every single reward the shard mates collect can and will be used to make your life harder in arena. Why allow this to happen unchallenged?
The thing that drives me crazy is the notion of that payout time is an entitlement. You collect what you win in arena. If it was intended as a daily freebie, wouldn't they just give everyone the loot?
