For squad switching countries is not easy. There are many reasons why it is so. My squad for example has in rules that we fly for bishops, and prohibit side changes, because when majority of squad flying for one side, and someone for other side, it is often "spying" talks and so on. We need to vote for rules change and side switch, and that can't be made at once. To avoid spy talks you have to switch all the squad at once. Again, it is a problem, because people not all log at same time, they log during the day, and it may be that squad will eventually splitted between countries. Also, even if it is agreed to switch, people understand the loyality for their side differently, so it is possibly creats intersquad problems, when someone will not want to switch at all, or even can get out of squad. There were examples when squads were destroyed by one or several side switches.
Same with my squad .. so we suck it up, either way, and don't whine.
I think that perk multiplier do not work. Bishops had numbers before it, and had numbers after it. They started to lose numbers when they lost the coordinated teamplay and some "country spirit", and I am not sure it has much to do about perks.
The quote above and the one below, especially in italics, are at complete ends of the opinion spectrum.
On one hand you say is doesn't work and on the other hand you have explained exactly why this perk system was developed and you like it because its a good thing for the outnumbered countries.
I personally like the perk multiplier though, it gives the smaller side something, which makes them compensated for their numbers, and forum and channel 1 are free from endless country numbers whines.
