In their current state, runics feel like some of the most unrewarding content, when playing them as intended.
Even with the changes to search, runics with a group are often extremely unrewarding financially.
This is almost tied back into two main problems: Player competition and RNG.
If another player/group has recently cleared a runic ahead of you? The rune chest, and the smaller chests have nothing in it. If you accidently bring a player along who has cleared a runic recently? Nothing in the rune chest.
If the chests have been bashed, whether runic or individual chests, you also get nothing from them, depending on the timing. And they take even longer to respawn, so a player without OL/DT, you are actively harming other dungeon-goers by playing.
Runics are made even worse by RNG. Not only can the runic chest often have a very low value piece, but the ore at the end of the dungeon is also randomized. (I'm aware the ore randomization is a bug, and used to persist, but there seems to be no action taken to fix it.)
I feel like this lootbox aspect is a really outdated form of dungeon rewards. If this is going to stay, some sort of trade-up system would be appreciated. Or actually scaling the rewards towards the difficulty of the dungeon. Easy runics have the same rewards as hard ones, and it just feels bad.
