Hello members of 343i, this is my very first post into this awesome forum, but i'm not writting this to introduce myself.
The real reason behind this post is to make an awesome idea (atleast in my mind) about matchmaking characters.
I mean, you should be able to choose between SPARTANs-II, SPATANs-III and SPARTANs-IV, each one with their unique HUD and armor permutations.
The S-II model could be taken from Halo 3 model, the S-III from Halo Reach and S-IV from Halo 4.
If we stick to the evidence and research, the S-II would be the most powerful SPARTANs, but we can get rid of that giving all the SPARTANs the same health and shield points, so everyone could choose their favorite model, and make them almost the same height to give a more balanced enviorment, so the changes are ascetic and doesn't needs to give any advantage from model to model.
Thanks for your time
