I have to agree with Limecat, "If it ain't broke, don't fix it". The new method could work if it wasn't hidden away at the very top and it didn't grey out everything you weren't using.
Firstly, with it up at the top it honestly is harder to glance up to. Before I could run and take a glance at both team resources from the middle of the screen, the place I was already looking at before I pressed tab. It being in the middle also allows me to also see through the leaderboard at where I'm going whereas now I ca;t keep as much of an eye for incoming vehicles because I'm looking at the very top and trying desperately to read greyed out values.
Next we have the greying out of anything you aren't currently using. Why? Why was this needed? I can understand greying out the zeroes but for the love of god what was the idea behind greying out the other numbers? If I'm running around as infantry I now have to stop and properly look at the resources to see how many more tanks I have to look out for or how many APC's they have left. If i'm just running around it's now a struggle to even see if the have vehicles left. In the 10-20 matches I've already played with this update I can't tell you how many times already I've glanced at the count, seen a greyed out value, assumed it was 0 and closed the leaderboard. Honestly if they changed this so the only number greyed out was the zeroes I could deal with this new system.
Finally, moving the resources to the top removed the name of wherever we're fighting which I have used quite a few times before in cases where I'm talking to people in war chat and asking for resources. It was handy to have an now you can only see it if you are dead and are not hovering over anything. I would like to be able to see it anytime I hit tab.
So it is fixable but at the end of the day, there was no need to get into this mess in the first place. We had a system that worked, as system I still prefer and instead of seeing zeroes you could tell they had run out of something simply by seeing that its icon was no longer there, no need to look at any numbers.
