That (doff nerfs) relates directly to another problem that we experienced quite nakedly in Warframe. The developers noticed (and by "they noticed" I mean "they'd been stewing glumly about it for years") that ancient dragon bittervets had piles and piles and piles of every type of crafting resource lying around, and also that even fairly recent recruits were able to grind resources far more quickly than they had apparently anticipated when originally designing the game's F2P model. It's quite clear they'd always wanted to monetize the (massive ripoff) resource packs from the cash shop, or at least more so than they were able to do.
Therefore, they pursued various harebrained tactics. Firstly, they tried a number of times to nerf Vacuum, which is a mod for sentinels (companion creature) that slurps up drops from the ground in a radius. Without this, you have to walk pixel-fucking-perfectly over each and every drop, so you can see how drastically a Vacuum nerf would have reduced overall resource gain (and increased player tedium). They've had to back off from nerfing Vacuum every time because the player base simply will not put up with it, in part because Warframe evolved to be a much faster and more airborne game than the developers originally intended, so slugging around on the fucking ground for each and every drop like a God damned marmot is a load of bullshit.
They couldn't nerf Vacuum directly, so instead they introduced an entirely new currency alongside a new expansion, replacing an old system in the process, which requires players to walk directly over drops to collect. This didn't do much to force players to not have fun, but I suppose Digital Extremes exacted their emotional revenge on the mean ol' players who don't want to sluggishly collect every fucking drop off the ground.
Then they dropped a real nuke and remade the entire game map, "coincidentally" removing all of the good old XP and resource farming spots in the transition. They pitched the new map (which included genuinely fancy new graphics) as a massive boon and upgrade for players, but any bittervet who wasn't retarded could see that nothing was given, mechanically speaking. Except for the graphics, the new starmap was a loss.
Then DE turned their beady Jewish-Canadian rat peepers to the huge hoards of dragon treasure bittervets had collected over the years. The next time there was a new content update, they gated a featured weapon behind a clan project that required an absolutely absurd amount of resources for any decent-sized clan to complete, based on the size of aforementioned dragon hoards. Just to give you an idea,
Lazing Dirk and I had been playing for two years, accumulating piles of this resource and using almost none of it, then suddenly our clan needed 20x more of it than he and I could have contributed if we contributed our entire stash.
That's when we left the game. See, if you try too hard to force your bittervets to buy that shiny new weapon from the cash shop, they might leave. Stick to making vanity items, dumbfucks. I personally spent hundreds of dollars on that shit in addition to grinding/buying and selling like a fiend and then buying yet more of it. I'll buy cool vanity scarves and armor and shit, but don't get too cute with the actual gameplay-affecting shit. The real news, though, is that making shit so obnoxious to grind that even bittervets can't do it easily makes it functionally impossible for new players to grind, so you're at threat of losing both bittervets and new players if you get too greedy.
As for all the technical issues Cryptic never fixes, yeah, I'm not surprised. If it can't be monetized, they aren't going to bother. DE was the same way with Warframe, and Warframe is one of the most successful F2P games on Steam/in existence, barring dotas and shit of course.
