I have tried T3,S3,H3,D3,L3,M1 in many SP games b/c I want to learn via experiments whether this setup is competitive.
I got to these scales following this logic - D3 is thematic and also Abysia has some advantage in it (food and taxes) that doesn't apply to its enemies. Now if you take D3 it kind of takes the point out of O3 right?- so there goes T3. Now you take out order and have high turmoil so luck 3 is a no-brainer.
Anyway this doesn't hold, usually Abysia is off to an awful start- lacking income, receiving not beneficial events (PD and gems are not useful at the start of the game) and sometimes also bad events. Then comes the first winter and cuts through your old aged mages. I was unimpressed with these scales to say the least.

I'd keep the D3 but change to O3 and L-2. Yes income will dwindle, but at least at a known rate and if you expand (which steady flow of income early on will greatly help to do) you could get more income.

Now, had Abysia received access to early game low level fire summons spell that summons "soldier" level units (for creating armies for early expansion - what with lack of income and low resource is not possible) and some fortune telling the thematic setup I mentioned above would have been much better.
Usually those fire gems just keep piling b/c low level fire spells are quite awful. They are marginally good for complementary units (fire drake) but not for making armies.
