About the Visual contacs, I'm not sure how this will work with 16km and similar mods.
I would love the inacurate WO firing solution. Together with a reasonable delay after asking for a solution. Always killed the immersion when the WO was able to spout his calculations faster than Einstein!
I use the WO on surfsace attacks for it used to be this way.
But if it opens more cans of worms, then stick to the things at hand first.
There is time for this later.
