I have an idea for a new general.
Basically whenever you attack a camp that has enemies such as Recruit Deserters and Bowman Deserters (any enemy that has a troop counterpart) then there is a chance that a percentage, say 10%, of those enemies will not die, but will join your army. The general would probably have a troop limit of 220 and also have the same perks as the Battle Hardened General (travels twice as fast and recovers twice as quickly from a defeat).
If you have enough room in your settlers limit then they would join automatically but if you were say meant to receive 10 recruits and you have 8 settlers left, then 8 of the 10 would be automatically added and the other 2 troops would go to your star menu.
This is my idea for how the chances could work:
88% Chance - No enemies join your army
8% Chance - 10% of the enemies join your army
4% Chance - 15% of the enemies join your army
To put all of the above into context, lets take one of the camps from 'The Black Knights'. One of the camps has 100 Militia Deserters and 100 Longbowman Deserters. When you attack it, if you get the 10% ability mentioned above, then you would get a mixture of militia and longbowman added to your army with a total of 20. This could be 18 militia and 2 longbowman, 20 militia and 0 longbowman, or vice versa (because 100 militia deserters + 100 longbowman deserters = 200. 10% of 200 is 20). If you get the 15% ability mentioned above then you would get a mixture of militia and longbowman added to your army with a total of 30.
One another attack in The Black Knights, you are up against: 50 Cavalry Deserters, 50 Elite Soldiers Deserters, 50 Crossbowman Deserters and 1 Sir Robin. When you attack this, if you got one of the abilities above, either 10% or 15%, then you would get the chance, but the Sir Robin would not be included as there is no troop counterpart for that enemy.
I hope that all of that made sense. I will be happy to answer any of your questions!
