There are nowhere near enough loadouts given the number of weapons, Warframes, companions, appearances, operator configurations, landing crafts, air support, etc.
At legendary 2, with all purchasable load out slots unlocked, I only have 21 load out slots. That's not enough. It really is not enough. At a minimum there should be enough load out slots to have a loadout for each Warframe. Some Warframes though, like Nova, could actually use more than one loadout; one for slow and one for speed. Likewise, there are A, B, and C configurations for warframes that change everything from mod configuration to Helminth abilities.
Load outs need overhauled too. They should include:
*air support
*landing craft
*landing craft appearance
*operator appearance and gear
Maybe I am missing some information, but it doesn't make sense to me to limit players to so few load outs with so MANY possible combinations of weapons and tools. Is it a technical issue?
