Why are you suggesting this.. Its already implemented via
PURGATORY
Thats right folks
PURGATORY
Pergatory has 1 AT generation, and no transfering them in any way.
Army size too big? Not a problem just sell off that extra UU for extra naq, $$, kill them off, or give be a kind soul and give the UU to one smaller than you (LIKE ME

).
So if you want limited AT, then come to the part of the game that has that
PURGATORY
But wait, do you think there are lots of people, like 500 or so who want limited AT and don't want to lose large army sizes?
Then ask the admin to create PURGATORY 2
In effort to allow the admin as little work as possible, there will only be 2 differences between these purgatories.,
First, the max 25(did that get changed to 50?) million army size you will have a minimum 25 million army size.
2nd difference is since this suppose to a more permanent style of play, while the first week will allow free changes between realms, after that the realms will have drifted too far apart and will result in 30 days worth (instead of 5) of AT to switch (going BOTH ways).

Disclaimer, having 500 people sign to go into pugratory 2 doesn't guarantee that the admin will make another purg. Admin is in no way obligated to make Purgatory 2 even if 500 people vote for it. Additional differense between purgs can be suggest but as before Admin will be under no obligation to do them and more differense you request resulting in more work for him will only hinder your chances of purgatory 2.
Any starting chances of getting purgatory 2 are guaranteed.
