...Now you can do whatever you want, but in the end, it's about doing more for less. Does the strategy work with the least amount of effort/knowledge/micro.
Now i will take Lenny's NKVD guide as an example ( no offense Lenny i love you baby). You could probably achieve the same result by calling in heavy tanks that can demolish the eneemy rather than microing the crap out of conscripts and your nondoctrinal tanks. Why spend so much effort trying to keep your fragile units alive when an ISU152 can just wipe out enemy squads for you with one shot. it's all about doing more, with less.
Sometimes, you can't force something that is broken/weak into becoming a viable unit.
More for less...Well that is the POV that is killing any kind of diversity in the "meta". Oddly enough more for less implies that you do more for a lesser result. I believe you meant less is more, implying using people want to use less skill to achieve a greater result, that of victory.
That there is how a stale meta develops, Lenny's guide is MUCH less predictable than the current Soviet reliance on call-ins. Predictability is a major reason for game loss. It allows flow, the ability to launch attacks from multiple directions, as well as feints to draw units out of position for ambush tactics. It is a rare breed in the current state of the game.
I find most peoples problem with CoH2, is they still expect it to behave like CoH1.
Also I think you'll find most companies don't give much consideration to the average gamers opinion of balance, as usually but not always it is biased.
