First, the Altar Seal that is supposed to automatically pick up progress orbs doesn’t really work, or at least it should work differently because currently it seems like it just increases your orb pickup range.

Second, one of the seals makes elite packs drop one extra orb, which is great, except it seems to be multiplied by the number of party members. It shouldn’t be. It’s way too OP and it makes solo play even more miserable in comparison.
