I'm curious why people use that option. I've never considered it because I imagined it would lead to what you experienced, which is a total blowout. What's the advantage to it that makes you choose that option?
I like the spirit of the option and use it because I think it's a more reasonable model for tech trading (vs no tech trading at all or all out tech whoring). There should be no advantage - just more fair trading (matter of opinion, of course) of techs and more control over how techs you give or trade are used. For ex, if I give a good military tech to a vassal, I surely don't want my vassal giving it up to a potential enemy, and that kind of thing.
In theory, the AIs *should* be able to tech just fine and there should still be room for trading.
In my experience, the AI can't keep up on tech because they seem to spend way too much on espionage and because they expand recklessly and early. AIs also seem to build fewer cottages in BTS.
Anyways, you pretty much have to bump up the difficulty if you want to use no tech brokering.
It's kind of sad to me, because I think the no tech brokering option is one of the coolest things to happen to tech trading in any of this style of gaming (I wish galciv2 had it too since the AIs in that game abuse tech trading horribly). Hopefully it'll be improved.
