				 Arena Season 14 Rush 
 Starting midnight (server time) of Friday the 9th, the arena final rush will  begin. During the rush heavy participation will  be   required by teams  to solidify their place at the top. Teams will  need   to play at least 4  games a day (starting that Friday, PRIOR to  rush)   to avoid rating  decay instead of the usual 1. Due to the   multiplicative  nature of the  decay, a team that wanted to avoid rating   decay for 2  days without  play would need to play 16 games to avoid   decay, 64 games  for 3 days,  etc. Teams are best off playing as many   games as possible  (4 a day  keeps decay away!) because there will be a 50% bonus to all rating increases during this final rush.
 Rating decay is more significant during rush week as well. Teams will     lose 5% of their rating each day they fail to meet participation     requirements as opposed to the usual 2%.
 
 The rush will last until Saturday night on the 17th when at midnight    the  season will come to an end, and teams will no longer be able to    queue.  The following day we will record the winning teams based on    rating and  give rewards.
 
 Remember, the week after a season ends you can get tempers on items 2     tiers above normal due to  a lessening of the rating restrictions. So    save up your tokens and try  to get a high-end temper on your favorite    item that would normally be  out of your reach.
