Making changes to the races and personalities, actually is not that difficult. Basically no matter what changes you intend to apply, you just need to achieve 2 goals: "Temptation" and "Struggling".

Offer a race some pros, that can give the players the urge to try this new changes out, but in the other hand, give them some cons as well, the cons that is severe enough to make the players struggle. Struggling, but still are not willing to let go of the race they want, because the pros given is just too temptating.

If you can create this kind of confusion with the races changes you made, then it already means you has succeeded, I don't think its actually anything complicated and needed to be put out a table of maths calculation to show the reason why. After all, when players choose races to play, they choose the roles that they are interested to play with. Not many will consider their choice by making a full page of maths calculations.

But the point is, you got to have confidence with the races and personalities you have made in the first place, and believe it:

There is nothing wrong with your races/personalities

Don't keep on modifying the race by taking the wars from the top kds as your references. It is the imbalance quality in the players between the difference of an average kd and a top kd, its not the race itself is imbalance. Through these years and ages of race/pers modifications, no matter what modifications you made, when they fall into the hands of the super kds, there will never be a balanced race. No matter what races you give to the top kds, they will always have a way to make it imbalance.

This is the past pros you had kept on adding to the Faeries.
1st time: +1 def
2nd time:+1 def again
3rd time: +pop back (enable possibility of offence attack)

May I ask where did you obtained the proofs that Faeries are unplayable? Have a look at all the kd pages, I can't see any of their Faeries are dead? No one been razed to 100 acres? No, almost all the Faeries in the kds are big and strong, high in honour somemore. Every Faeries in the average kds are big and strong. Flip the kd page and you can find a tons of them. So which exactly is the kind of kds are left to be said, that the Faeries are unplayable. Its only top kds isnt it?

You have to understand, top kds wars are all extreme. They are called top kds, thats because they are formed by top players. Every online games will have these kind of players, top 10 ranked, elites players that is. Imagine when all the top players gather in a place and fight a war, how can that be simply judged as the Faeries are weak and unplayable? Extreme wars, makes extreme cases, that's all it takes.

May I ask, if the next age, the top kds found a way to abuse your Faeries again, what more would you want to add to strengthen them? I maybe able solve the puzzle for you now. There is really no more focuses left to be added.

You see, all bonuses
- Wpa
- Tpa
- Spell Damage
- Thieve Damage
- Population
- Highest Defence
- All racial spells

All already included in one single race, Faery. The only thing left is what? Just offence, what else more? So can it be assumed, that you might want to give them highest offence the next age?

Elf is strong at magic, but he is vulnerable in thievery. It is the NM spells that makes it imbalance.
Halfing is strong at thievery, but he is vulnerable in magic.
The other attacker races like Avians, Dwarfs, Orcs, Undeads and Humans are strong in attacking or income, but they are vulnerable in both magic and thievery.
While the last time Faery are strong in defence, Wpa, and Opa, but they are vulnerable in population, which make them easier to be overpopulated.

May I ask that, what is the vulnerability of Faeries for this age? What can a -3 General make this race vulnerable, from which sides?

Is it from Mage?
Thieves?
Offence?
Defence?
Population?

No, nothing at all. This race has totally no vulnerabilities this age. They just can't make more than one hit, thats all. Everyone can see that easily.

Full defence Elfs existed in the game. Full defence Halflings also existed in the game. They are also full t/ms that can be also brought down by a 130 Opa Orc. They also can't stop the Orcs from keep on attacking, like you said. But that doesn't seems to bother you anyway. Its only Faery that you are paying an attention to. Come on... even a kid can know you are favouring the race.

After 3 months of using a same age, we are really anticipating for something new to be tried in the new ages. Kindly please, don't keep doing things like this to the utopia's only one age's races changes.
