My point was clearly towards the second half of your statement: OKW can build a Kubelwagen (even two if you want to stretch it) to avoid spamming infantry and keep resources and population available to build elites. They have both options: Spam Volks or delay with Kubel and get more elites later.
You're stretching what I have posted. I did not make a statement about changing JLI timing, nor about you saying JLI did not have utility at all.
In my opinion you understated the value of their current abilities. I have to correct though that they were spammed after a patch when JLI were lowered from CP2 to CP1 (not CP0 as I originally said) alongside a multitude of buffs.
What you have quoted was a response to Looney suggestion that JLI should remain as is but move to CP 2.
At CP 2, with 100 sec CD, (no infiltration) trying to delay in order to use JLI as core infantry does not seem be very viable.
I on the other hand have suggested that these unit should become more focused on utility than damage and become support units with lower Pop/cost.
Which suggestion do you agree with?
Back to the main topic:
I think overwatch is fine overall. It was a horrible commander back when flares were auto-placed at every territory point. This was in my opinion the biggest nerf to the commander. The sector assault should be tuned down though and made cheaper. Even with AA it is hard to counter, because there are so many planes.
The flare change seem to rather hard, they CD on rearming the flare should simply be significantly increased now the ability is hardly used.
Alternatively it could be replaced by conscript's flare with no damage or low cost (or no cost) "sniper" flares launched from trucks.
