Sniping by nature is a covert and stealth. I would like to see the following added and deleted. IMHO.
All small maps like Uncaged and indoor maps like Reflection be removed.
Atom to be abolished forever from all playlists
Outdoor maps only (Pinnacle as the smallest) Paradiso, Utopie, Abridged, Renegade, Highlands, Tempest and Temptation, Hemmorage, Spire, Boneyard, Wayont and Trident would all be good.
Reduced team kill count to 25 or 30 kills. People will camp in snipers. It is what snipers do.
Cammo and Hologram to be the only AA.
No secondary weapon or grenades period.
And the real controversial one. Make them reload after each shot to stop the spamming body shot kills. You want a true one shot kill then it has to be a headshot.
