i give you guys props
if you truly want to do it no matter what the penalty
I SAY +1 with a penalty that will keep people from wanting to change sides and avoid them being able to take command of carriers and what not
For me at least, carriers mean virtually nothing. I rarely fly anything other than German planes, which are not available on carriers.
The biggest issue is right now, if I change sides to the low side (I would rather be ganged by enemy than fight green guys for kills) and a squaddie comes on, I have to wait for 12 hours to go back to the side that they are on. By the same token, if they were to switch to the side that I switched to, they are also stuck for 12 hours.
In addition, there are times that there is not much of a fight to be had on the country that I am on, yet there is a huge battle in progress between the other two countries somewhere else on the map. The problem (for me at least) is sometimes you switch to get involved in that fight and it only lasts for an hour, then dries up and you are stuck.
