Dwarf Sage/Merchant is one of the worse combos in my eyes. My arguments are bellow:
- it is an elite dependent race, it requires heavy elite pump to be efficient - therefore, it is diminushing the war capacity (being ready for war ASAP). A dwarf need heavy pump to be efficient.
- you can't pump both wpa and elites in same time, assuming a 4-7 days real pump for a 15-20 epa (30 banks/30 arms) or a 3-4 wpa (80-90% guilds)
These two facts make out of dwarf one of the slowest combo possible.
War Hero is far better than sage, both in early and late age. Even Warrior is better. And i take in consideration strictly the bonuses:
33% sci effects - War hero from Count and above beats that 33% sci effects bonus. Even warrior beats that if you consider the 20% OME is multiplicative over all the other OME. You can test the numbers yourself.
Assume 33% science over a 15% housing science (let's not go extreme numbers for late age). That will translate into a 20% housing pop. A 10% military sci will become a 13%.
War Hero add 5% pop as a Count and 5% OME. So it is already better than Sage... if you consider the drake immunity and 12% elite conversion it is FAR FAR better than sage.
Warrior 20% OME has the same results >>> beats the sage from first second OOP until end of age.
Merchant? it's a joke of personality. You will have 100 peons in war to ToG with.
Unless you plan to go explorer and in this case, ToG works well for "peacefull godly experts" :).
As for the Dwarf: his BE capacity is a drawback for me. Allowing the dwarves to overdraft into 80 and even 90% makes easier to kill the province. Overpopulating such overdrafted province is much efficient than a 60-65% drafted one.
