I think it's the other way around. CB is bad first off, but the counter argument has always been to move. The fact that that isn't the case and that CB can still gettcha is the icing on the cake.
Sander says it only saves you 3 clicks (each and every single time any sort of shell goes up in the air mind you) but no amount of clicks I have ever made have allowed me to follow units through the fog of war. It requires no effort AND it cheats but the cheat is on top of requiring nothing from the player, not secondary to it.
People here are getting almost outraged if Sanders or someone else says that tracking is only an issue in very rare circumstances and then instantly insinuate that stating this equals defending it and most of all defending the whole CB itself. It's just nuts.
Back to topic, but I can only say what I have already said before:
The thread started out as purely focusing on the tracking. It then widened a bit to CB in general which is fine by me. But many here start mixing both issues into one another to somehow "prove" their point.
Most Allied units barrage for quite some time. I have not tested it in game, but judging from what Elchino wrote they will usually be counter barraged during their barrage or at the end of it. And assuming that the barrage finishes and the Katy/... starts moving before the LeFH is set up, there is a decent chance that the Katy will be in the cone half way, so the LeFH barrages an empty spot half way on the map. If your vehicle is still in range at this time. There's a lot of conditions and in most circumstances, shift queueing your unit back to base will do exactly what is should do.
Is it still possible that you drive your Katy back to base to be barraged there? Yes, but rarely.
Is this whole tracking behaviour stupid? Absolutely.
Is it worth the drama? Nope.
This behaviour has only been discovered just now. But suddenly this is used to state that CB is OP because it tracked (no personal statement of mine on CB intended here). But this OPness went unnoticed for years, so it probably is not as a huge deal as some make it out to be.
So to sum it up:
Tracking is very stupid, CB a bit stupid, LeFH ability could use a redesign and all of this is blown out of proportion.
