2 suggestions 
  
1) Anti Camping to lesson the spawn camping. 
2) only 2 Tubes not the 5 or 6 we have now, 
  
I think if we have more Helicopter , ac 30 , or what ever that will do 2 things , help the better players get more kills or increase the camping to get them, 
  
Get rid of the XLR stats or ajust it, I asked a couple of the regulars that used to run gun why they are camping now , Answer was to increase there standings in the XLR stats, 
As it is now you can in a corner and 13 -1 and be at the top XLR standings, So the run and gunners that get killed a lot drop down in the XLR standings,even though they finish higher at the end of game, Just promotes more camping and spawn camping , 
  
just a couple of thoughts,
