This is exactly why I have already joined a clan. Those wonderful moments when ppl actually join forces are so rare but very powerful. I wan't more of that.But I have to disagree with you about infantry hiding beheind rocks. If I see someone standing still they soon regret that. The aim in Renegade is very acurate trust it. When it goes red press fire!
Why infantry is so hard to get with a tank is because they are so tiny and move so fast it's almost imposible to time them so you must shoot the ground instead and since it's AP rounds it won't do much damage. If there was some HE rounds it would be great against infantry.
