I was looking at Fabricate and was almost offended at how useless I feel the spell is as written.  For a magic spell, I feel it should allow (with the casting time and relevant materials on hand) the crafting of basic armor and weapons.  Jewelers and highly ornamental weapons and armor I’d agree with disallowing, but to require proficiency in any crafting tool on top of the spell plus resources defeats the point of casting it in the first place.  Most of the things you can create RAW are the most basic items you’d never run out of in any town.  The one exception I can see would be the Bridge, but I’m a little unsure about how long and strong the bridge you could create would be.  I’m furthermore bothered by limiting the creation of things made out of stone or metal.  It really seems this spell should be able to create (with enough materials) basically any Equipment in the PHB.  
Would someone be able to argue against this and otherwise sell me on the Spell or, failing that, suggest how else the spell could be changed to make my ideal of the spell legit, be it longer casting time, a higher level spell slot, or additional material components?  Or do others generally agree with me?

Uses of the spell requiring no proficiency:

Make basic table and chairs at your campsite.

Fortify doors.

Seal entrances.

Turn gems into gem dust or vice versa.

Turn iron scraps into ingots for easier carriage. Or turn iron into caltrops (don't need proficiency - they're just bits of metal with jagged points, and used to be made by untrained people all the time)

Make basic shapes out of anything. 

Steps/ladder up otherwise umclimbable surfaces.

Combine with Mending to fix anything.

The spell is definitely better when you have proficiency because taking any basic raw material (and DMs can stretch what is meant by "raw") into objects in just 10 minutes is far outpacing any regular crafter. 

And getting proficiency is not a concern - some races start with a variety, Tashas options to exchange them for ones you want makes it even better, and then there's backgrounds and so on. Getting some good proficiencies is easy.

What would take a very long time to make you can now create in 10 minutes. 

It's the D&D equivalent of a money cheat.

Note also, there's no "rolling" to see how well you make something with this. You can always make the best version of the object your proficiency would allow - as if rolling a Nat 20. Bearing in mind that you could invest 200 gold to make a glyph of warding storing Skill Empowerment and give yourself expertise for an hour. At 8th level you could cast this twice, within Skill Empowerment's duration, to create 2 objects. Then use Catnap to get a short rest for an Arcane Recovery, and cast a 3rd time, still within Skill Empowerment's duration. 

3 objects made at maximum expert level in under a hour : something that could, depending on objects, could have normally taken anywhere from a few weeks to a year, otherwise. 

Find lots of broken swords and weapons? Melt them down. Make ingots. Fabricate into new weapons. 

Get paints, and painting supply proficiency, and make brilliant art. Or forgo hours of decorating with 10 minutes spellwork. 

For some characters and players this spell can be amazing. For other games it's probably never used. But that doesn't mean the spell is useless.

Okay, thanks @Cyb3rM1nd, I appreciate that.  I suspect my own players will make rare use of it, but there you go.
