The dissadvantage of a Flak88 that would take skill to use is when a base was under attack, a newb would come in, grab the flak88(cuz it is a big gun) and hog it til it gets destroyed(unless it were perked). Still would be a fun and feared gun when used properly.
And Napalm and High Drag/Para-frag(whatever you call them nowadays)
dont seem to be specialized bombs. Specialized bombs are the Grand-Slams Earthquake bombs, V2 guided ballistic missiles, Kamikaze Japanese planes, Atomic bombs(we could get these and destroy a entire arena!).
I think Napalm and High Drag/ Para-frags would be usefull when used properly
and would be a nice addition to the A-20 or B26s inventory!
