Priest/trader imbalance, is it really different than the other combos?

[Penchant]

The priest/trader class combo has been not allowed because of too much benefit, but how much different is it than the advantage it has with other classes?

As do I. Especially since food is automatically transferred, now. Back then, alright, sure, priests didn't need units to protect their caravans and their max travel times was 16 hours. But now nobody needs troops to protect their caravans and there is no more travel time limits. Priests also get less hours now with age.

Everything that used to make priests far superior traders than warriors is now gone.
