I would like them to overhaul the crafting system and make some kind of new crafting mat that requires tons of mats or rare mats or some kind of conquest-like challenge to get the mats, once per week that would allow you to either upgrade an ancient to primal, or at least have option to choose a specific item type and have the game roll a primal for it. Example: you get the mats, and now you choose daggers, the game then poof gives you a random primal of dagger type.
this would be nice to get a little more bad luck control, and not saying getting the mats would be easy, maybe make the requirement doing a 90 solo, and like require 100 souls, 1000 of each mat or something on top of that.
This would make it not available right away in a season, at least for first week or so for those elite players, and have something else for players who take their time to shoot for, and then look forward to rolling it each week, even after you have finished your normal build.
They should overhaul the crafting system to make gear that scales with your level, like heirlooms in wow, that grows with your level, special gear that as your paragon grows, your stats on the gear grows or something.
They have so many options, and there's so many good suggestions on a daily basis that could be done, but we get...s12..now with new wings...enjoy!...i enjoy the game still but its extremely stale/old now, harder and harder to log in each season, the ONLY reason i even am playing s12 is cuz of the buffs and updates to old builds, and its amazing...but what then for s13? will be it s15 before we get another massive buff?
Lastly...buff drop rate or alternative way to get Ramha's Gifts...i'm para 430 have yet to see a gift drop, people saying they are 700+ never seen one...insane disparity for that item when you need them on a regular basis, they shouldn't have that huge of a drop rate difference, some people get 10 in a few days, others NOTHING for WEEKS...i understand rng and luck but that item specifically seems to just be an oddity, went weeks without one last season, then to have them drop like candy for a week, then nothing again rest of season...intended?
