What if:
When you build a weapon, its level is set to what you forge level was when you build it.
But you can add just as many forge point as your forgelevel allows it, without using a BP, but you cannot go any higher than what the level allows on which the BP was build.
Each forge point could cost... 2000 gold?

The result i think is that you feel like you are actually making progress on your chosen weapon, rather than constantly waiting.
And you will still have to farm for BP if you want the weapon to have higher stats, so they should remain as they are, even their current gold price would make sense with this, unlike as it is atm.

Also, your current BP drop system is still jank.
You try to encourage teamwork and team comps, but you HAVE to play as the raider you want the BP for, encouraging ingoring team comps for just a chance at that BP.
Often being the reason you have a terrible team comp and match, as most people REALLY want that BP.

I was trying to extract with my team, then i noticed that circle that fills up when extract were going REEEEAL slow.
I didn't make it with my team, got overrun by Wardogs.

What if:
When you build a weapon, it has that set lvl.

I enjoy the game a lot.
As of right now i have spent 166 in the last few weeks and i have enjoyed myself in the gameplay itself.
But i do find the extreme amounts of gold required take away a lot of the fun to me.
I feel like there is no progression happening at all, because even though i have almost every BP for each chatacter, i can't build them until after at least a day or 4 of grind.
1-2 for a common and 2-4 for a rare. That is way, waaaay to much. And i dont mean just on and off grind, i've been grinding intensly this last week with 6+ hours a day.
And i have build ONE weapon, trying to get enough for a rare.

And why can you get dupes? Way to make it feel like the 20+ min you just spent in a mission was a huge waste. You could at least have made it so you would get gold instead, to help towards another rare BP you have laying around?
I have been trying to get the BP for Bloody Mary this entire week. I have spent almost every rare BP mission on Doldren for the hopes of getting it. Patient Boy again, and again, and again, and again, and again, etc.
It is that sort of RNG the puts me off in every game, not just this. You can do everything right, make sure everone had a great time too. But the numbers was not in your favor so fuck you, here's another Patient Boy. Oh you already have it? Then here is nothing and some Faction Points you already have way too many of.

Make it so that you get more gold from lvl ups, the current amount is nothing you care about at all, simply because there is too much grind. It gives us no interest what so ever when we get it.
We could also have it so that for every min we get like 100 or 50 gold more.
My average games go on 20 min and i get about 2000 gold from it, and atm i want to build a rare BP to 90.000 gold. Let us see how many hours and then days i would need to play JUST for a weapon.
15 hours and that is about 3 days of playing the game for me, JUST for a weapon.
That also means i have to ONLY play this game and NOT have a life on the side for about a week just to maybe get a 180.000 character.
It frustrates me to no end, and it is slowly pushing me away from the game.
I have found myself thinking "I really dont wanna bother with this shit gold farming today, what else can i play?" more and more. Simply because the grind does not feel rewarding in any way to me.

And some people want a specific character, like i want Doldren and bought him before Spacelords, luckily.
But now, oh my god, i would not even have played to the 50 hour mark because i would see how much gold you get per mission and then look at his price and be like "Nope, i ain't gonna deal with this shit no more".

I think what you should do with the system is to make it so that no character has their own price. Make the price the same for all, starting out at the lowest possible and then increasing with each purchase. That way you can get the characters you want without having to spent possibly a weeks grind. And now you have your desired characters, the grind for the rest is not so bad anymore.
Just keep the prices per increase as they are now, the last few will all be 180.000. I would be able to handle that now i have the characters that interests me. And if you later want to release a character that you dont think should cost 180.000, add another "step" to the increase.

I understand the game is now F2P and that you would like for us to buy the gold. But in my case my wallets is closed shut the moment i feel strong armed into buying things.
I think i have spent hundreds of dollars or euros on Warframe, because it is something i can choose and the grind feels rewarding. And i am happy about it too. I did it because i felt like they deserved it and i wanted to support them. But because i feel strong armed here, i can't make myself do it with good conscience, i probably will do it for a skin but i will feel terrible for doing it.

I am stuck in an endless loop. Even after a restart.
I got out of a succesfull mission and was asked to reconnect to a mission.
I did and it would say "could not join mission" and sent me back to the menu. And then it would start over.

As you can probably guess, this is rather annoying.
