Maybe if it didn't require 4 clears of a nonetheless obsolete dungeon (hour+ queues here) just to be able to then purchase the weapon with tomes, we'd see a lot more up-to-date weapons among casual players?

Personally I'd just like to see more ways to get weapons at this point, such as easily known challenge modes or achievement bits within dungeons over ilvl 160.

Another thing that would help is of course more accurate ilvl weights. If the ilvl of your weapon determines so much more than the ilvl of your rings, then weigh it accordingly.
