Do you microadjust your lens?

My Sigma 35 Art worked well on my 6D at medium range distance, but focus at infinity and wide open was a bit off. I never found it an issue because I shoot wide open only on closer distance and infinity more from 2.8 upwards.

However, I recently bought the Sigma Dock and did a full calibration. It took me about an hour for all distance brackets to compare live view with the normal AF. I had to dial in +10 to +14 corrections on all distances which surprised me.

I haven't corrected my 2 L lenses and the other Sigma 85/1.4 EX. They all seem fine and I am not paranoid to check them all.

My 18-35mm definitely needs adjustment but I I mostly set my exposure/focus in Live View anyway so in general it doesn't bother me. I also have a very used Sigma 85mm that I got for a steal of a price but has a really scratched front element so it exhibits horrific chromatic aberration. It also sucks at focusing through the OVF but I don't know if that's due to the scratched element or if it just needs AFMA, but again I just use it with LV and it focuses just fine in there.

I know it's something I should do but since I shoot a lot on my tripod it hasn't really bothered me too much yet

I usually do not shoot smaller f number than 2.8 with my full frame camera. I also do not pixel peep. So do not feel the need for MFA.

Yes I do. I've found MFA to be critical for me.  I've managed to make most of my lenses focus better with it, some lenses brought it back from 'unusable' status. My old 80-200L has severe back focus on every body I've ever put it on. On a 5D it was terrible because of this, downright unusable unless shooting at f8. On newer bodies I can make adjustments and it works beautifully.

Most of my lenses have benefited from MFA corrections. Some only need a little, some need more, but now I absolutely will not buy a DLSR that lacks this feature.

Yes, but fear not, MFA can only get better (more automatic) over time and no enthusiast/pro cameras will ever get without MFA.
