Though, I am starting to get wickedly accurate with rifle gernades.
I advise keeping your aim in. When I first started playing ET I spent most of my time with the nade launcher and too developed a lethal pinpoint accurate aim. You can’t beat the feeling of satisfaction when you see a guy in the distance running to the objective, you predict his path, tilt up just the right amount and fire, dropping a nade right on his head.
Alas, I have been playing medic a lot lately and so have lost my aim
I still get the odd good shot, but I don’t have the eye for it anymore. I would recommened you stick with it - there are hardly any players skilled at nade launching. It’s a very useful skill to have, especially when playing as the allies and you need to clear defensive positions. Sometimes it’s more useful than a panzer because you can bounce it off walls.
I miss my rifle nade days
