What Tana said there.

This way players actually plan where we're cashing in their limited Crafting Levels on without needing to go through the hassle of putting everything into a table and cross referencing the recipes and levels, as I have tried to do in the Wiki but it was really, really tedious to the point I couldn't finish. Especially when the game doesn't give a hand and say what you can do or not beyond "yes" and "no".

A more practical example was me trying to decide if I should go balls deep into Toolmaker when wanting to be a Blacksmith Engineer for thematic reasons, I wouldn't know the level needed for crafting Bombs, so I ended up leveling more than I needed and bam, had to redo my stuff once I saw it was impossible to do anything beyond 5+1 and 2~3 on another. I just don't want other people to go through this, or have to direct them to the Testing Server every time they have a question about the game.

That said, how about a hover-over pop-up like you made in the Skill Tree menu? Place mouse over, displays the level of the recipe.
