Why not make every/most of the items tradeable?
I play this game for 3 years now, i've done so many Maelstorm Arena runs and i still didn't get Inferno Staff, rng sucks for me, at this point i feel heavily demotivated to even continue trying.
Why can't i buy the Staff?
I remember every time i grinded through a dungeon for hours or even days to get my gear,
Why can't i buy it?
It wouldn't ruin dungeons because people who could afford gear would buy it and people who would want to earn money would grind gear and sell it so dungeons would still be full of people, the same goes for trials.
The only reason i could imagine why you wouldnt make every gear tradeable is because most of the people would stop buying your DLCs beacuse they could buy the new gear instead of grind it
