Hey Halo fans 
My idea is that in your spartan customization you should have the option to choose from select spartan II and Spartan III armor (helmet and armor) 
  
       -Halo 3 (spartan IIs) 
 
Mark V 
Mark VI 
Rogue 
EOD (my favorite) 
Hayabusa (whatever happened to this one? One of the coolest) 
 
      -Halo Reach (spartan IIIs)-Helmets only because some of the other pieces werent that great 
ODST   -Helmet and armor 
HAZOP (Reach style) 
Commando-Helmet 
EOD (Reach style) 
Grenedier 
Scout (Reach style) I think it looks better than the scout helmet seen in both Halo 3 and 4 
 
  
I also think that they should put skulls back to when you had to find them. I liked going in campaign and doing that. Or maybe they could do it so you can use them but there are achievements for finding all of them (it would also be nice to get armor pieces for finding them all) 
  
Please leave some feedback if this would be a Yay or Nay in Halo 5 or just comment
