Some native servers still have the option to use autoblock turned on (remember, it is built into Warband from the git-go)- you have to turn it off manually on those ones. But anyhow, autoblocking (not that I buy into your hilariously outrageous accusation) doesn't help you with positioning, it doesn't help you know when to attack, it doesn't help you chamber, it literally helps you block. And if you really need help blocking in this slow-as-molasses combat speed mod then it's 100% PEBKAC and honestly given the average player skill I don't think it'd even be a huge advantage by any means.
Everyone can just block (though some choose to NBOH, an honorable path to be sure) because it's not hard at all unless you get deked by a microhold or are doing multiple v 1 or have too much sweat or cheeto grease on your sausage fingers. Most people can reliably chamber and block incoming chambers nowadays, which is a lot different from when I started playing Native in 2010 lol, and even from when I started playing cRPG a year or two later.
My advice is yeah, do the needful, download and install an autoblocker. I look forward to the disgruntled unban request thread talking about how "EVERYBODY ELSE FLIPPIN DO IT". Feckin topkek m8s.
