There has been some debate over numbers in the Main arena about how rooks are severely outnumbered.
This is very true but note the following stats....
as of 11:11 EST +/- 1% due to constant killing in main.
Rooks Kills: 32765 vs all 28776 1.14 KD
Rooks Kills: 15345 vs Knits 13062 1.17 KD
Rooks Kills: 17430 vs Bish 15720 1.10 KD
As you can see if attrition was factored Rooks are kicking all others tails.
Note the other slob countries:
Bish kills: 44441 vs all 47652 .93

Bish kills: 28703 vs Knits 30207 .95
Bish kills: 15720 vs Rooks 17430 .90
Knit kills: 43289 vs all 44077 .98
Knit kills: 30207 vs Bish 28703 1.05
Knit Kills: 13062 vs Rook 15345 .85
As you can see clearly Bish are by far the worst proforming bunch in the game. Even with their Hordes they can't even crank a positive KD ratio.
Note to HTC you have the data as shown here to create simple attrition model.
Perked plains should be cheaper in the country that is most efficient; likewise they should be more expensive in those countries who expend the most resources. Perk planes should count as 1.5 factor of the attrition model. hence for 2 perk planes down would be the same a 3 normal planes.
This model kills two birds with one stone. first off.. the perk planes will balance the numbers issue with superior planes going to the efficient side... Second the arena will most likely balance as a result of those who want to fly perk planes cheap and will shift countries. Then when one country gets to powerful the attrition model will balance it self do to dweeb factor loosing the perk planes at a rate of 1.5 to 1.... it will also have the hidden bonus of thwarting suicide attacks, hence increase acm and people actually have incentive to land their kills...
MA arena is saved.
just a suggestion.. And a razing to slob Bish and Knit who cant even break 1:1 but then claim how uber they are... more like suxor....
my 2 cents...
