this wouldnt work well... sure its depending on your refine... stars of ninja and so on... older servers will still have a advantage up to the point where you near to max... but to be honest i also dont like arena at the moment cause i usualy fight 2 or 3 ppl the same time.... 1 win 1 lose and so on i cant rank up cause i always get the same enemys and if i switch my team.... suddenly a new guy comes who counter the lineup... sometimes i also get 2 or 3 times the same enemy... sure if i lost before i usualy will lose the other fights too... its annoying and a change would be nice.... but i also know there will be no change so we have to go with it
