Once upon a time, before the MA's were split into the different arena's that we have now, I would have said country jumping was bad. Stay on one country, keep the numbers' consistent, try for balance, keep the gameplay good for everyone.
However, the way the setup is today, even with ENY factored in, balance is seemingly impossible. And the effect of the balance is worse, when you see the lower overall arena #'s. When you have fewer people in an arena, you don't need as many over one side or another to make a big difference. A 'horde' can be comprised of fewer people, and still have the same effect.
I know Dale (Hitech) Split the MA's to try to fix a perceived problem with the gameplay. But it seems' like the cure spawned more problems' than we origanally had.
So now, I say please jump to balance...But please do so responsibly. Don't simply go somewhere else, simply to try to get the most squad base captures, or because one team is on a roll, and you can get alot of vulch kills' off of the 'steam roller' effect. Jump to make this game better for everyone. Thank you.
