The arena is a nice idea, but having the best team is not nearly as important as having the most tickets... It would be nice if everyone had a cap per week (or per day) and then it would come down to whomever can score the most wins in a row with their set ticket amount. Putting a cap per day would still reward those who login daily and use their tickets. Arena tickets would not need to be part of the homescreen bonus or randomly given out on boards either.
Just one possible solution here- but I basically I want to see a method that rewards best team.
