The maps are made well, and the shooting is amazing. Not to mention the amazing graphics. HOWEVER the maps do allow for spawn-camping. While these campers can be killed quickly, I feel spawns could have more protection.
you already have huge advantage when enemy is inside your spawn area, because enemy can't kill you first few seconds (spawn protection). Your idea about extra protection will not fix anything. It will only slow down game and both teams will camp on one spawn area, or another.
P.S. If you have ideas and you want to suggest something, do it in forum.
