Half agree half disagree.

Disagree because, as we all know, current jewel system needs to fixed first, not bring gems back. If gems are coming back and jewels stay as they are, it will be a mess.

Agree because, like you said, there will be always hoarders and only riches will use para and eye as new gears come out. It will be better to give everyone to farm them again. Jewels fail to take the fisrt place of end game atm. Continuing current jewel system and limiting para and eyes will only cause more imbalance.

I like the idea of crafting jewels. If we could craft any same level of jewels, it would be interesting. But drop rate must be increased in this case.
