First off, the lockers are named Standard Field Locker, which would lead me to believe there should be Field Locker, and possibly Special Forces Field Locker. Increased cost, increased gains.
Also because of the fact, every listed or shown item in Customization is purchasable, except the 3 Trophies for the Predator, and we all know there are also “Hidden items” such as new knives for the FT as well as Shaders for the knives, and Unlisted trophies for the Predator. Why are some shown, some hidden and some unpurchasable?
I believe it was a major missed opportunity to associate the higher tier (Exotic and mythic) with in game achievements. Killed 1000 Fireteam as Pred? Here’s the Warloard shader. Claimed 500 full trophies? Here’s the skull and spinal trophy. @IllFonic already implemented this with awarding you the mythic skins for Fireteam at lvl 100, it would be nice if the look of you Characters was based off your play as opposed to how nice the RNG was being with you on any particular day.
I’ve been 100 since 2 days after release, have all but 2 Achievements, and have unlocked all but 60 Fireteam items (not including hidden items) and all but 94 Predator items (once again excluding hidden items). XP means nothing to a lot of players right now, so most games turn into, How much V can I get before we face off with the Pred? Because if I want those items I have no choice but to grind out V.
It would just be nice if playing the game and doing things awarded you for the effort.
