Ah finally, a set of refines for units I don't have. Among units before CYL1, this leaves Eliwood, Seliph, Ryoma, Ike, Xander, Valter, Camus, Reinhardt, Olwen, Delthea, Hector, Sonya, and Julia as the only units without a refine (side-grades don't count). I don't think any of these refines are very far out of reach at this point though I suspect those DC weapons wouldn't get a refine until a major update, perhaps 3.0? I think they can also easily make a Dire Thunder refine that only helps Olwen significantly so I don't think Reinhardt is enough of a reason to not expect it to happen eventually. Not like Reinhardt is even dominant anymore though.
Looking forward to those new Abyssal maps though, I don't suspect they'll be that painful to beat unless they add reinforcements to the mix. The Abyssal maps currently don't add more reinforcements or enemies than Infernal though so I have my doubts on that.
