I am not a pro just love photography. I have canon 2ti and a 80D that have been using for about 2 months now. I do love the 80D and just was thinking about a refurb 6D. I like to shoot flowers,birds, Animals,car shows, waterfalls, people, well just about anything. At this time I have 3 lens that will work on the 6D, a 50mm 1.8, sigma 105 macro, and a canon 100-400 mk2. What would the pro's and con's be in getting the 6D. I am not looking to make a living from photography. It's just a hobby to get me off my butt.

6D would be a very nice camera for flowers, car shows, waterfalls and people who are posing.
It's not so great a choice for birds, animals and active people. It just isn't an "action" camera. It's AF is similar to that in your T2i, in fact.
Your 80D is a much better choice for AI Servo shooting. It also gives you a "free 1.6X teleconverter" effect for small and more distant subjects, when you're using that 100-400mm.
All three of your lenses would work on a 6D. But, any "crop only" lenses... which can be smaller, lighter and cheaper... that you might get to use on your 80D and T2i will not be usable on the 6D. It's pretty much limited to full frame-capable lenses.
But, what are you hoping the 6D will do for you?
Low light/high ISO shooting? 80D is nearly as capable, both in controlling high ISO image noise and it AF performance in low light conditions.
To see any significant difference in image quality, you'd need to make big prints... really big prints. Probably 16x20" or larger. There certainly won't be much difference in images posted online, at typical Internet sizes and resolutions. You will likely only be the only one who ever views the images where you would see a difference... at 100% on your computer monitor. But on most modern monitors that's like making a 40x60" print and then viewing it from 18 or 20" away!
There is some minor difference in Depth of Field. Not that DoF changes with different sensor formats alone. It doesn't. DoF is exactly the same until other factors change. It changes with different focal lengths, working distance and aperture settings. When using a FF camera, in order to frame a subject the same way as a crop camera you need to move closer or use a longer focal length, or a bit of both. So large apertures will appear to blur down backgrounds more strongly, when using a FF camera.
And at the other extreme with small apertures, because FF requires less enlargement, it's a little less susceptible to diffraction. So, you can use slightly smaller apertures with FF, than you can with crop cameras. The difference is about a stop at either extreme. In other words, large apertures appear about one stop's worth more blurred and you can use about one stop smaller aperture when seeking more DoF.
