1. Already an option, can't remember exactly where in options it is though. The final two dungeons of ARR being an exception..
2-3. Not gonna happen
4. Can't happen due to spaghetti code apparently.
9. Well thats subjective. I know people who love crafting in 14.
10. I agree, but I assume its something technical
11. Shouldn't be an issue if you use weapon loadouts. I highly recommend them
12. Would be cool but I assume spaghetti code is to blame here too. If not, they should add it
13. Not sure what you mean
14. Also not sure what you mean with useable items. The 1handed/2handed staves isn't really too relevant to fix because post50 they are only 2 handed
