I know this has been said before, I know fan boys come up with all sort of creative explanations and deny others to play the game differently, but I'll say it again.
PLEASE LET US BUY NEED MORE LOADOUT SLOTS
Many players including myself, use one slot for each warframe. It makes a lot of sense. I always look for weapons that fit the warframe in style.
I can buy everything with Plat. Why not more loadouts? Being at max MR + purchasable slots should always equal the amount of frames in the game.
I'm at a point where I have more frames than I am allowed to buy loadout slots. And I just can't go on. I can't just trash a frame because thats what it would mean, I'd choose a frame that I play least anyway, and probably never touch it again. I'm not the type who "mains" the most OP frame to cheese the contest most efficiently. I value the creative effort that goes into all of the frames and all of the weapons and I want to give myself a diversified experience. You're sabotaging yourself if you deny players to do this. It's almost a deal breaker for me and a reason why I stopped playing for a long time. I just came back and am facing the old problem.
