As someone who's done all quest Solo without any help or platinum to use as a shortcut, I think this could good but it can also be very bad.
10 years of content is definitely difficult to catch up on if you're a new player, so a few skips won't cause any harm if the price is fair number. A price you cannot use a coupon on as a double shortcut.
The issue is here is that what makes Warframe good is its unique storyline and its already mostly unknown to alot of people specially newer players. Other than that its just constant grind for MR then just extra stuff to make a profit off of. So if there's gonna be a "skip" button which means they know absolutely nothing about the story behind those quest, then what's the point of catching if they're gonna be confused afterwards? Confusion and lack of understanding normally tends to make people quit games.
🔸️In my opinion, One of the solutions is to add a new page that has short stories behind each quest followed by maybe a few images for demonstration. Something accessible for everyone to read incase they skipped or its simply been too long since they played a quest that they forgot everything about it.
🔸️Another possible solution turning solo quests into multiplayer quests so newer players can be assisted by others if they got stuck somewhere.
🔸️Last solution (best one) that comes to mind is not adding a "Skip all" option but to add a "skip mission" button. If there's a tough to beat mission like a boss fight or defence (anything that requires a little bit of endurance) due to lack of mods and endo to make a decent Frame/Weapon/Companion build then it can be skipped to the next chapter of the quest while still being able to see the remaining cenimatics which let's be honest, it's the best part about Warframe. So no lore is being skipped. You'll have all the knowledge you need.
Other than that, requirements to complete the starchart, open junctions between planets and acquiring more quests could be reduced.
You cant instantly teach newer players that they're gonna be catered for. That's never a good start. 🙂
