AutoCAD 2015 is complete garbage

So our office is in the process of upgrading everything to the new 2015 due to our subscription that i must say we are getting ripped off.

We pay thousands of dollars every year for new autocad / revit suite and for what?  NOthing but garbage.

The new autocad doesnt work for crap.  half the commands arent recognized, its slower than crap and i must say i feel ripped off.

Its slow, sluggish, ddedit doesn't even work to edit text.  Unbelievable.  Anyone have any ideas of where to start.

I have go things working better by turning most every feature off but its still very slow.

This is what i get for when i type DD for the ddedit.

Select object: Unknown command "DDEDIT". Press F1 for help.

then you type out ddedit and it works but it takes forever to thing about it.  Unreal! to say the least.  Autodesk is turning into complete garbage

Oh and most the commands you have to type in at least twice in a row for it to start recognizing them.  

This isnt only on one machine either, its on several
