Your little base class guys will run around and do their thing gaining levels and soon they’ll enter kind of a next tier or upgrade stage; some classes like the Farmer and Carpenter just keep getting better well into Tier 2 make new and cool stuff. Meanwhile other base classes can be upgraded into exciting and new classes with the right base level and new talisman they’ll transform. Your Tier 2 classes will last a bit longer than Tier 1 (Eventually you probably won’t have any Tier 1’s except Carpenter and Farmer and possibly Herbalist) getting new skills and equipping new armors/equipment and some classes just plain start in Tier 2.
So now you’re leveling guys taking your Warriors out and slaying hordes of enemies but this world is always moving forward and your Warriors won’t always be as young and nimble as they were; soon they’ll get older and with that an increase chance to die. But… but… Anzu is a wrecking machine his Strength and Stamina are off the charts! He’s like a god among tribesmen; so you decide you want to retire Anzu before some Skeleton does it for you. The choice to put a high level Warrior out of the game is a hard risk; but with all risks there is a chance for a great reward. Anzu will find himself a lady friend (who’s also been retired) and soon you’ll have yourself the first of the next generation; this new generation will receive bonuses to two stats based on the Primary (First stat showing above the Tier 2 class boxes; the second stat is the secondary stat related to that class. Each class has two stats that directly influence their skills and abilities.) stat from each of their parents (unless the parents are of the same class then it will use both). This bonus will be a base 10% of their current stat (example) with a random -4%/+4% modifier (example) so it won’t be constant and can be amazing… or crappy.
You can choose to put a tribesmen out to stud anytime you want but they will need to be a master of a Tier 2 class if you want the possibility of unlocking a Super Awesome Elite Tier 3 Class 
So in our previous example if you put out Anzu and say Karzu the female warrior while at master level you’ll have yourself your first Champion; this Champion will grow up and make it rain destruction on all those who oppose her and when her time comes you can put her out and her kid will have a random chance of inheriting either one of her Tier 2 classes. So Tier 3’s can possibly make more Tier 3’s but will always at least make a better than average Tier 2.
So now you have active tribesmen and some that are just retired and they might have multiple kids; but they’re still getting older and they’ll eventually die. It might be from old age, for females there will be an increased chance of death while having a kid as they get older, or it could just be a random working accident around town. Just in case you were thinking of making baby factories or if you were wondering “What the heck man? Some retired tribesmen taking up space in my town?!” Once someone is retired they’ll be able to perform all non-class related functions just like a regular worker bee or classless villager.
If you read all of this stuff I’d love to hear your opinions on 1) If it makes sense how I said it, 2) Does it sound fun?, and 3) Do you think it would be too complicated for someone to figure out?
I tried to fit as many “you really need this class to function as a town” type of classes inside Tier 2.
