vote for #2, as for the same reasons as other. number 1 might be affective, but i bet few would like to join an arena and then sit in the tower waiting.
#2 is good, if a squad wants to fly together so badly, then they can all just move to the lowest number country. so i guess that takes care of the "i can't fly with my squad/friends" argument.
the problem with #2 from what i would assume lynx may have been getting at, is that if one country is losing with fair numbers, and many just log off, then the imbalance is created by the losers quitting. but with #2 the winning country could still retain its numbers, but could not get any extra numbers.....why would they need it anyway?
#3 though i'm sure is easier, would lead to everyone complaining. looking through the past years, someone was always complaining about their country being outnumbered....and it's happened to them all for significant time periods. eventually we will have just one overwhelming horde demolishing everything in its path. no challenge, no gameplay, just huge numbers of people vulching/fighting 4 v 1, and bombing buildings all day.
your game, i won't be the one telling you how to run it:) i think we all appreciate the amount of time and effort you and the AH team has put into this game and the effort to make it even better. after reading the message boards and seeing some of the things i've seen, i'm sure there must be days when you feel like saying "ahhhhhhh f it."
