I have all the recruits I need for each specific builds (I have a separate save path for each LI, and I tried the different combat builds for the first few of these I did). The only build I'm able to make any progress on is Seidr. The other two are massively challenging, as resource management becomes critical while trying to level up the two skill trees while also making sure I don't fail the main quest of food supplies. And even with sufficient points in the individual trees, some combat encounters are beyond frustrating. My allies have the gear and/or resources they need and I follow the recommended combos, but still the enemies regenerate hate at an unsustainable level or cripple my fighters to the point of useless. If there's something I did wrong in my builds, even after following guides and recommendations on Discord, the fact remains that combat is crushing, hence my original comment advocating for the super casual gamer.
For now, I'll just retrace my steps for the LIs that are not on a Seidr build to re-do them as such since the struggle is way too much for me on the other two builds.
