Marketplace Content - What would you like to see from the community?

What I would love to see and I think is lacking in the ue4 community is the existence of detailed and very well tutorials that are geared towards more than just the bare minimum. Tutorials that cover parts of the engine that baffle people with artistic ability for things like level design and little aptitude when it comes to even visual scripting through blueprint.
I would definitely pay decent money for someone to take the time to make a great tutorial on something that just isn’t covered. Such as complicated character movement systems that switch between walking, running, sprinting, crouching, prone, leaping, covering, dodging for a FPS/TPS game. Or a tutorial that sheds light on making a movement system that is completely unconventional and helps people to better use blueprints to achieve personalized results from ue4. For example say upon being engaged in 1v1 melee combat with swords, your character becomes locked on the enemy and conventional movement switches to a system where you circle each other and your character always faces the enemy, after combat finishes conventional movement takes over.
I would much rather be taught how to, say, make an inventory system with a very comprehensive and detailed tutorial, than have it just for me, with little knowledge of how it works and be scared to touch it. I’d pay the same amount of money or more for the former, the latter, from experience, can be difficult.

I feel that if people had the to make a profit on a tutorial and not just post to , that is a great incentive to share one’s knowledge with the community and empower smaller developers with less technical skills to learn to use the engine far more effectively. I am well aware of the tutorials and documentation on ue4’s website, but I do think it isn’t enough. Especially when most tutorials cover what is mainstream to make and doesn’t get built upon further than the basics.
Does anybody share my thoughts that a paid tutorial program would encourage the growth of the knowledge base of the community?
