Point blank, this is the actual current issue not just endgame players face. Newbies will want to get anything upgraded aswell, and then they notice very quickly that they cannot even ATTEMPT it on a daily basis, which is just demotivatinng if you spend (let's say it's a fast one on average) 1.5hours just to get all the relevant dailies done for gold.
For people who thoroughly enjoy the gameplay and want to spent their time, it still doesnt event feel rewearding to do it with multiple characters, as they will still funnel all into a single one, while not getting anything out of it for days, weeks, potentially even months if unlucky.
And im just mentioning to do it on 1! Character.
Lets say you would want to get a 2nd or even 3rd character reasonably geared (not for actual endgame): You would realistically not even attempt upgrading anything; as it currently is you would only get the new accessoires, keep them at +0 and theres that, since upgrading them to +6 is wasted gold as new tier will make them irrelevant again.
While Aerodrome and Substratum were the ongoing Demonsbane dungeons, with the first "True" accessoire, there also was a more decent chance at farming said "True" accessoires as the barrier to entry of farming the minimum stage, was manageable for a good amount of people, as just playing actively would get you there after some time.
With current demonsbanes, actively farming Stages 12 and above (for the "true" accessoires) will require a huge amount of gear (which most of us cant even upgrade due to gold income), resulting in a very low amount of people even able to clear, let alone reliably grind those stages hundreds of times for the bare minimum chance of even obtaining them. It's just not even encouraging when you know you don't really have even a chance at farming them.
Enough rambling, as we need solutions that would not instantly "break" the economy as you per usual take (way too) cautious increases:
Since we already have "dynamic quests" (and i am not referrign to the daily limited dynamics) from hardmodes give gold, why not give the lower difficulties low amounts (like the current hardmode 10 gold), to easy mode, and make bigger jumps for higher difficulties.
As a small example:
- Easy: 10 gold
- Normal: 30 gold
- Hard: 50 (or even 100) gold
- Demonsbane (Stage 1-5): 10 gold
- Demonsbane (Stage 6-10): 30 gold
- Demonsbane (Stage 11-15): 50 gold
- Demonsbane (STage 16-20): 100 gold
This would give people an actual incentive to play the game more than just daily quests, and maybe the ocassional demonsbane multi groups, on top of actually giving us a chance to upgrade stuff slowly, even if we fail 30 or more times on a single accessoire stage.
Potentially it might also be a good idea to add the Starcross and/or Skystealer upgrade materials to dynamics so people could have the necessary materials for attempting the upgrades aswell, as they are heavily daily limited as Carbon already mentioned.
