I too disagree about grass. It's as it should be. Gathering it into bundles and stacking it fits. I wouldn't throw it into a bag where it would bend and break, I'd bundle it and lay it somewhere carefully where it would be available to weave baskets and make long strands of thread or twine. Fairly realistic to me. If it's not something you like doing, as Darkwalker said, trade with someone who does. There are many ways to work with others and trade in Xsyon, if you don't like picking grass, but like picking rocks...find someone who is the opposite and team up, trade the resource that you don't mind gathering for the one you need. I know there's ppl who would trade their grass thread for your granite or limestone.
As for shovels....of course they should remain a weapon. In an apocalypse, we would be grabbing whatever we had to get the job done. I'd be sharpening up that spade to swing wildly and smack things very quickly. :D They aren't necessarily better than axes....different yes, better tho... that's a matter of opinion. Axes swing & charge faster while shovels are slower to swing & charge. Axes have a shorter range while shovels have a longer range, again....as it should be. (compare it to a one hand weapon vs two hander in most other games (with a slight tweak); quick with shorter range vs slower with longer range...damage can equal out if used properly) Blades....they're quick, but you have to get in real close to use them. It all seems very much realistic to me. Blades do perhaps get the short stick in Xsyon (tho I know of a player or two that proved that skill could even average that out), and while I look forward to having more than just quality lvl as a factor to our weapons, the ways and reasons they work as they do, seems on track.
Backpacks, eh, travel takes enough time as it is, if ppl travel far to scav/trade/pick a rare resource/explore/visit friends/whatever and a bear wallops them....they're not gonna be happy to have to return to get their items. It would just stop map travel which is finally starting to pick up again and he's right, would just cause more complaining than benefits.
