The problem seems to come from just how drastically the MTTH plummets.
Code:
mean_time_to_happen = {
months = 260
modifier = {
factor = 1.2
trait = content
}
modifier = {
factor = 0.75
learning = 10
}
modifier = {
factor = 0.75
learning = 9
}
modifier = {
factor = 0.75
learning = 8
}
modifier = {
factor = 1.4
trait = cynical
}
modifier = {
factor = 0.2
trait = ambitious
}
modifier = {
factor = 0.4
trait = zealous
}
modifier = {
factor = 1.1
trait = detached_priest
}
modifier = {
factor = 0.75
trait = scholarly_theologian
}
modifier = {
factor = 0.5
trait = mastermind_theologian
}
}
modifier = {
factor = 0.2
trait = ambitious
}
Ambitious? It goes down to about four years to happen. Ambitious and zealous?
One year. Oh, and is your learning the minimum for not triggering the 'raise trait' ambition? Now down to less than a year. Ah, and of course ambitious
gives you Learning. So it's far, far,
far too easy to reduce this.
If you meet all the reductive traits, you get a MTTH of 260*0.2*0.4*0.75^3, or about eight months.
Gardener/Impaler can only be reduced to 166 months, Duelist/Poet requires that you be single and can at most be brought down to four years by being
just a Charismatic Negotiator (better? Nope!). Skilled tactician about eight years. Hunter starts with a MTTH of 360 months, and then can only be reduced by 0.75 without having two nicknames. Celibate/Hedonist can only be brought down quickly by being a... tier 2 scholarly education and gregarious, which is a ridiculously specific combination. Female falconer/poet (or is it hunter/poet?) shares the exact same modifiers as a male hunter.
All in all, the problem is that Scholar has its chances reduced by: 1) desirable traits, 2) cumulatively by minor learning boosts, whereas the others tend to be only boosted at
all by very specific educations.
