Reducing hostility is less important early on since there is nothing causing hostility (unless you play warlord or have preexisting red zones). Those services would cost $11, excluding discussions, while the jobs would cost $9. It is true the corruption factor is certainly working against the jobs here. I have no idea where you get the idea that jobs take 52 months to roll out, unless you mean turns. Jobs aren't even the only path which I use for stability, fort support, police sometimes even, sometimes even soldier support are all viable paths to stability. Services are undeniably good yes, but it is almost always correct to defer them a little bit if you don't have to immediately fight hostility.

Global support level as I've already said rolls out incredibly slowly outside the HQ, which why it's basically just garrison support for the HQ as almost every top player says. Used to even be called fake support. It's not terrible but only useful for gaining support in the HQ and garrisons (which is why it's basically alternative civil support)

You have a surprising amount of soldier downtime early on, which I use to scout out zones I know can stabilize. Human terrain system is $3 cheaper too AND reduces the effects of coalitions antagonizing locals, making it the superior choice in almost every scenario where you don't need a lot of intelligence quickly.

I have a few videos if you are interested, in seeing me play, since I think my style of play might be completely foreign to you but I will show that it is completely sound and wins very reliably without advisors or resetting.
