Yes, you're talking about changing their roles right? I feel like paths are a great unit for 1 CP. 2 rifles into an officer into Path is a valid build. But imo JLI function more like "elite" units thanks to the ambush skill and therefore I think 2cp is a much more reasonable timing for them.
Paths have been 1 CP before and no one build them. The main problem was and still is that USF is strongly funneled into building Riflemen. At the same time, building the officers takes ages, too. This usually forces you to build 3 Riflemen to keep map presence, 2 Rifles into an officer is possible, but usually not advisable.
You'll probably reach 1 CP at 3-4 min, which often coincides with the time you'd roughly get an officer and having no free MP to spare. Unlocking Paths at 1 CP was bad, because most viable builds will already have 3 Riflemen out there. If you build Paths next, you'll delay the officer and thereby a potential support weapon and you LV timing. If you build the officer first and then Paths, you will usually not have the MP to get a support weapon.
Also, having 3 Rifles, an officer and Pathfinders will also strain your MP economy a lot. 5 combat infantry squads is only advisable in special builds.
Other factions can afford having >1CP infantry due to multiple openings (early MGs or light vehicles like Kubel and UC). But not USF.
Making Pathfinders CP0 was a very good idea, but badly executed within the frame work of USF.
