Not sure what your point is. If it comes down to builds, I agree that UKF is a bit bland because of they are missing the indirect and a second LV, so their tech is quite predictable (especially in the current meta).
I do think thats the point. Isn't it always 3-4 IS + maybe an UC (or seldom a vickers) into Bolster + Sappers and 6pdr into AEC (maybe add a Landing Officer or sometimes Sniper)?
Emplacements are another failure, with the exception of that one good placed (screened) mortar pit. Bofors and 17pdr are rarely seen (atm Bofors gets locked out anyway). That whole concept can't hold its ground.
Then you have to lock out either Comet or Heavy Engineers/Churchill. In fact you go either for Comet or Heavy Engineers.
Lets have a look at the other allied factions: If I play soviet I play all 8 units of T0, T1 and T2 in different matchups/maps. That alone is a diverse starting. Its similar when playing USF, sometimes you go Lieutenant, sometimes Captain. That alone are completely different decisions that lead to different playstyles.
For more diversity:
- Sappers in T0 with some extented combat utility
- maybe Anvil/Hammer shouldn't lock out the other units, but only the other abilities (same approach as for Bofors/AEC)
- of course UKF needs an onmap nondoc artillery unit (still hope for another solution than extended mortar pit)
