Agreed.
Also, Engineer gadgets need some love. Right now there is no reason to not run the RPG. So, there is a ton of RPG usage, and it makes them a serious threat against helicopters (I know because I do it frequently).
I'm not saying RPGs need to be nerfed, I think they are actually in a good place (against vehicles, it actually needs a small explosion radius buff against infantry I think); but there needs to be something that draws some engineers away from running the RPG, because maps with lots of engineers are over saturated with RPGs.
If the Javelin were better, I bet many would use Javelin instead of RPG against tanks (especially "Tank Snipers"), and it would lower the volume of RPGs on the field (which would ease up the amount of RPGs being shot at helicopters); but as it stands, Javelin is hot garbage and you are better off just running the RPG.
