The REQ System is fine, and it works - it does not exploit anyone and it is fair.
But NOT with customisation.
Weapon skins in REQ packs, I am ok with, but armour customisation in REQ packs, that is NOT ok.
Ever since Halo 3, your armour showed how good you where, or what achievements you had unlocked, and you are more likely to play a game much longer, if there is something to work towards. Lets say that there are 200 pieces of armour to collect in Halo 5, (I know this is wrong, just roll with it) only about 10 of those are unlock-able through completing the Campaign, or watching Halo: Nightfall, or something through Halo Waypoint. All the rest of the 190 pieces are through random REQ packs.
This is the issue, even Halo 4 had commendations to complete to unlock the best armours. I feel that this is what Halo 5 is missing.
I would go by the Titanfall Multiple Customisation System, if you like the game series or not, you have to admit that the customisation in multiplayer in TF2 is the best out there.
You work hard to level up weapons to unlock skins that stand out, and the same with skins for your Titan and your character, this is what we want in Halo 5.
'Member the days of Reach, were you where only a Sargent and you saw someone with the In-climate Weather effect, and you decided to play and play until you got enough credits to get that piece? I do, and I still don’t have enough to get it to this day!
I just hope that we have commendations like Halo Reach and that this can be used to work towards unlocking armours, along with levelling up.
