food is easily stolen without being a hybrid and 3% farms is probably a bit low for any non-undead. With that said if you are an A/T hybrid and you main use of your thieves is stealing food, runes and gold your missing the point of hybrids, typical their goal is damage to the growing attackers via ns/peasants. If you are stealing gold/food/runes to run your OWN prov you aren't helping the kd and it would be far better if you simply had the extra offence.
Then perhaps I could run slightly more farms and towers. As for not helping the kingdom, the extra leftover resources gained from stealing can be aided out to the rest of the kingdom, hence why stealing is both damaging the enemy kingdom and helping ones own side.

"stealing" via runes/food/gold should be done by the attackers in you kd that are getting the worst land gains. Your attackers steal from the people u let grow(low tpa), while hybrids control growth and while pure t/m shell out the attackers. If you are running 6-7 mod tpa to steal 30k gc/5-6k runes every 12 hours you are hurting your own kd more than you are hurting theirs. There's just no point in stealing from the mid teir attackers as they just wont have enough to make your gained resources worth more than the damage a ns could be doing.
It would be far more than 30k gc/5-6k runes every 12 hours considering the increased effectiveness of robbing during war. As for hurting the kingdom, that is why I suggested 3 hybrids max, so they wouldn't completely deplete all the targets for stealing.

In every prov i've ever run a heavy attacker has had better science than a hybrid simply because more offense=more learns mid/late age. with that said even if the two prove have ~equal science since more t/m science=less pop/be/income science the attacker/hybrid are simplistically at a wash when it comes to science.
That is true, and I agree.

Unless u are a halfer thieves cost more than dspecs and when being chained your going to loose most of your thieves/dspecs. sure thieves dont require income, but the net damage done/recover time to your prov is more when u loose thieves. And if you were stupid enough to run a higher draft rate becasue your thieves dont cost wages then your going to be even more screwed as you overpop faster. go ahead and run 80% draft rate becasue u can pay your army, all that means is you are going to cry when chained.
But a hybrid can pull off 100 OPA with 70%-75% draft.

in a proper "deep chain" your going to go be hit down such that you dont have space for your peasants/wizards/thieves until your army gets in with the new land. As your dspecs and thieves desert but your wizards dont your going to loose the majority of your dspecs/thieves. In fact since your army deserts by 10% of the population you are over 115% pop the more army you have in theives (becasue u ran that higher draft rate) the FASTER your army will desert. The only part of your army that u can be sure wont desert when overpopulated are your leets/offence since they cant desert while the army is out. Then u have a choice while your army is out you can keep either your theives/dspecs. if you keep those theives your going to be at zero def and people are going to throw all spare offence at you and your gone. If you keep some def (as much as u can) than the extra offense u have (as a strait attacker since your not over poped when your offence gets in) is a major asset because u can quad tap with that offence a LOT longer than a hybrid who started with 30-40 less opa.
The hybrid runs more GS and thus less overpop than a heavy attacker in the same position. The hybrid could easily release most of his thieves and spend the rest of the war as a heavy attacker.

thieves cost more than dspecs, fortified doesn't lower the cost to train thieves but it does your military. A well organized kd spams aid in the forms of runes/food to decay while not in war to even out tb. And all of that doesnt matter when at war becasue the only aid u need is gold/food. Even if you are being taxed at the max of 15% its not alot of wasted gold/food. (and i personally run 50% wages when chained because the increase in ME due to the constant hits tend to negate the need to pay 200% wages making your 15% tax on gc aid requirements basically a non-factor)
That is true, but what if the hybrid had some gold stashed away to maintain constant 200%? It would allow the hybrid to hit his way back up faster.
