The new repair system seems kind of hard. I mean, I have tailoring 8 and I still get occasional failures (damaged further) while trying to repair my military rucksack. It just makes me super worried that I might lose the rucksack if it goes almost-destroyed no matter how skilled my character is. The system seems also wonky and buggy. “Repair once” doesn’t seem to do anything until you perform it multiple times. I also managed to reinforce an inactive manhack, while I specifically commanded ‘repair, don’t reinforce’… and while doing that, too, I received failures. Mechanics and Fabrication both at 10, whichever is used in repairing manhacks. I can’t even imagine what it’s like in the early game now. Should be… interesting.
DEX and PER both 10… was that the problem then? Are they low enough to cause penalties in tailoring?
Does encumberance on hands, arms or eyes affect tailoring success?
Does lighting level affect it?
It just bugs me that I don’t know. Lack of complete understanding also makes troubleshooting and feedback difficult.
I’m a little conflicted and troubled about these changes, even if they worked perfectly… but I won’t be the first to scream to go back to the old insta-repair.
Getting new stuff to replace lost ones is such a drag, especially if it’s a high-end item 
But, like, whatever. I can debug myself a ton of rucksacks if “rough life in the Cataclysm” starts to feel like “OK, this isn’t fun or fair anymore”.
