The reason I stick to one country is because it's fair. My squad is there also, which is more important. I'll switch if I want to and fly with other people but most of the time I stay on knights. Through the easy fights and through the hard fights.
Country hopping is essential for balance but it is also adverse to balance. If there were no loyalies then every time a 163 base was opened up everyone would be flocking to get some easy kills with the rockets.
Maybe bishops have cheap perk planes going, so some people always swap to fly them. If everyone swapped to fly them at the same time as jonny side swap does then the price of perk planes is going to skyrocket instantly.
Essentialy, alot of people who switch sides all the time to get an advantage of some kind when they make the choice. this is only possible for them because other people stay in one country most of the time.
There are also alot of people who do the exact opposite, in switching the the disadvantaged side when they make there choice, so I am not trying to label side switching in general. Just explaining how a % of side switchers only get that option due to a core base of players who stay on one team.
If the intent of the thread is to make everyone a side-switcher it could not possibly work.
