Even I was able to suggest better ideas for bonuses:

-X/Y/Z% chance to have 2 units healed after a fight, half of your units healed or all your units resurrected. At level 80, chances are 45%/30%/20%. The higher the level, the higher is Z% chance and the lower are the other 2.

Max Z% is 25%. In fights of 2 waves, this effect activates in each wave.

- according to how much population you have available or occupied vs the total population you have in your city, you receive one of the next 2 benefits:

1. If your available population is 49% of your total population or lower, all your non GBs productions, attacks and defense are increased by X% X at level 80 is 15% and max % is 20 or 25%. In case of attacks and defenses " if you have 1000% of red attack, it increases up to 1150% if X is 15%.

2. If your available population is atleast 50% of your total population, X amount of buildings no longer require road connection. Those buildings are the biggest ones in your city. At level 80 the number of buildings are 30, max. Number is 50. Maybe at level 180.

- the more fights you do in GbG, the more negotiations you can do with 4 turns instead of 3 turns, the more negotiations you do. The more fights with no attrition you can do. At level 80: if you do 50 fights, you can do 25 negotiations with 4 turns instead of 3. If you do 50 negotiations, you can do 25 fights with no attrition. You need to do atleas 2 fights or 2 negotiations to active this benefit and the max number per day is 50. The max. Number, maybe at level 180, could be 75 or 100.

- this bonus is to encourage players to participate more in gbg, expedition and QI:

If you earn a reward in any of those 3 places, you receive those rewards x2. The chance increases if you have not participated so much during a day.

At level 80 you have 15 x2 rewards (can be more) but 15 on each feature; 15 in GbG, 15 in exp., 15 in QI. If your the first x2 reward has 100% chance and it decrease down to 10% for the last time. Max number of x2 rewards could be 30. Relics are not applied for this, the same for himeji/SCarrier rewards.
