As a DM, once initiative is rolled, I do not keep track of player AC, or any number on their sheet for that matter. I have a vague idea of their hit points, but I have a lot more going on on this side of the screen. Remembering if the fighter is holding their shield, or if someone has some special modifier applied to them is taking up unnecessary bandwidth. So I can take a guess that 29 hits your AC, but I always want to make sure.
My guy, you gotta learn to use paragraphs.
Maybe take a step back and consider if perhaps people are alienated from you not because they are inferior to you intellectually, but because you treat them as if they are. Your comment is a rambling mess that uses a tone and vocabulary that does not endear you to anyone.
