Drawing objects in Acrobat DC

Can you please add so we can draw, erase and add line/rectangles and common shapes?!?!? 
This is not acceptable. 
I was using a free software before my company bought Adobe DC to make this easier but ITS WORSE!!!
WHY SHOULD I PAY TO MAKE IT WORSE?

How can comments be a logical approach to making basic lines and shapes?? Even free publishing software is capable of this simple task, we're not trying to make a comment but a piece of design!

I used the convoluted hidden comments section to make a simple rectangle and the outcome is bullcrap in a form design its just not elegant, it does not act in the way professional use it for the intricate design!

Look we have to do our jobs very well, so why can't the Acrobat designers do the same especially for the simple things like Edit  add and PROPER 'shapes/lines'. Gee.

Why the drawing tool is buried in the comment tools in a mystery to me. It took me at least a 1/2 hour of searching to find this out. Very frustrating to say the least. If drawing tools was a separate item it would be much easier to find. Come on Adobe, you can do better than this!

The fact that I can't draw a simple box in the edit PDF functionality OR change the properties of my text box to add a background color is ridiculous. 

I use Acrobat to teach industrial print reading, One exercise involes tracing the energy paths of a fluid system which in previous versions was a simple a s drawing a line on a line. But now, every line I draw remains in an "edit box" and the properties bar stays grayed out until I draw another line. I have yet to figure out how to turn off the box so I can change colors and line-weights on the run.

WHY EXACTY WAS IT CHANGED. A PERFECT  FUNCITON AND YOU FOULED IT UP. IN THE COMMENTS SECTION? WHY? I DONT WANT TO COMMENT. I WANT TO DRAW A RED LINE. NOT COMMENT. I WANT TO DRAW ONE DUMB RECTANGLE NOT COMMENT. WOW. MADE IT SOOOOOOO MUCH HARDER TO JUST DRAW ONE BOX. AND FORGET ABOUT TEXT. NOT EVEN GOING THERE. CANT ADD TEXT LIKE YOU USED TO  AGAIN, THE COMMENTS SECTION (WAAAAA?). THAT NO VIRTUALLY NO ONE USES FOR COMMENTS BTW. BIG WASTE OF TIME. TOO CUMBERSOME. CHANGE IT BACK. DONT ANY OF YOU PEOPLE ACTUALLY USE THE SOFTWARE YOU WRITE TO SEE HOW RIDICULOUS THIS IS. SIT DOWN WITH IT FOR ONE DAY ON TEN DEADINES. THEN YOU'LL CHANGE IT BACK. 

Thank you, Sara.

Under Comments a box appears that says No Comments Yet. There are not options to draw a shape.

Yes we can draw simple Comment Boxes but Comment Boxes aren't Objects and as such cant be rotated or manipulated as Object Rectangles can. 

Can someone advise me as to what I missing and how to Draw Objects and Lines in in DC Pro, the Object Toolbar remains gray and inactive in Edit PDF mode?

Nothing happens when I press the tool arrow.  So I can't get the comment icon (couldn't think of a better place to hide it!).  Please advise.
