It's a common issue for an online game. :)

Sadly, there's nothing we can do. 

As everyone knows, the clan boss gains significant power when his health drops below 50%.  Since the boss resets in the middle of the night, people on the West Coast are at a huge disadvantage.  I can survive much longer when the boss has more than 50% health, and thus do more damage and get better rewards.  Unfortunately, even though I get up early (6:00 AM) PST, the boss I face already has less than 50% health, since all my East Coast clan members have already used their 2 keys.  A system that disadvantages players based solely on where they happen to live seems very unfair to me.

I think you are wrong.

What if your team is all Force Affinity heroes.

At over 50% health, The Clan Boss will be Void.

You will do neutral damage.

At under 50% health, The Clan Boss could be Magic

You will be at a huge advantage in damage.

Your team in this situation would deal more damage + stay alive longer vs. Magic Affinity.

This means you can't say you are at an Unfair situation.

You say you are in an unfair time zone problem, but just gave an example.

The example shows you are in favorable time zone situation!

Do you deny that the affinity change can help your team?

Player J, when the boss’s health drops below 50%, it’s not just a simple matter of changing affinity, but rather his power grows significantly.  His attacks have a chance to ignore defense (one of the most powerful abilities in the game), and he gains new buffs/debuffs.  The reasoning behind increasing his power at 50% is to make it much harder for the clan to down the boss and get the double reward bonus.  So, no, I would happily take a boss over 50% health.

The solution is actually very simple, The game should restart the CB each 25h or each 23h instead than 24. This way the advantage/dissavantage will eventually hit all time zones.

Wow, this is actually genious. I am most of the time sceptical about people giveing suggestions left and right, but this sounds actually like real solution.
