New suggestion for swarm server

Hi I will suggest some edits in the game , I wish you accept it
Firstly , can you decrease the time for humans to respawn, it's too long as 100 second when the game is actually 4 mins just , I suggest it to become like 70-60 seconds 
Secondly , I wish you add new uls like ak47 knife , new m4a1 ul and new snipers for normal players , also edit the damage of crossbow to become 1 hit 1 kill .
Thirdly , I wish also add some new maps because the server maps become boring when we abuse max and dust2 or inferno , I suggest add 35hp_4 , cs_milita , cs_assault new maps 
Fourthly,Remove the useless powers from powers menu ,
And thank you .
