Well, this isn't so much for me as it is for other people who play deadm all the time.
The banner (like the napalm one, and the invader zim one) in game got in the way on the first map I played yesterday. It was dust and I was running by bomb site A. I see an enemy by that short set of stairs that you go on for short A. I can't aim well at the guy though because the napalm banner is in the way of my view, I had no cover where I was so I just had to charge him and die.
Also, the banners that make noise annoy me when I only play on deadm every 3 months or something like that. I can't imagine how much hearing the same thing over and over annoys players who go on deadm daily.
Maybe you could at least change them to something new. I dunno, just thought I'd give my input.
