Factions - do you need to bother?

[WLFobe]

So I fought a war and ended up with four factions. Eventually they faded away, but it took some years. Then I fought another war. By the time that war ended, I had six factions, and one had gone to 30%. As soon as the war ended, I suppressed that factions and prepared to wait for the others to fade. It took a very long time, and in the meanwhile I needed to start a war.

Now I seem to have some pretty permanent factions, none of them terribly strong, but all persistent. Is there any reason to worry? As long as none are over 25% there's no effect, right?

 

[Chapter Serf]

As long they tend to stay low in population, I've never had an issue. However, if you force an empire to cede a bunch of planets at once, then all of those ceded populations will be in one faction and it could get strong very fast.

Now of only there was a real risk of problems from large factions:/
