I don't see the high end runics as a waste - as others have pointed out, the hammers will always make items that cannot be replicated with imbuing, as well as SE armor that's medable (and even regular armor that's not - most sampires could care less about active med).
Even Barbed kits can do armor that better than imbued - while it's more difficult, the barbed kits are now 1/10 or less the price of a high-end smith tunic (and some pieces of armor!), and relatively easy to get (technically, 1 in 9 small tailor BODs fit one of the EIGHTEEN larges that gives a barbed kit 100% of the time, and about as many that fit larges that can get the random upgrade.
I personally use a pair of barbed leather gloves with 4 resist properties and 17% LRC, that total more resists than the Kasa of the Ra-jin (also on the suit), and the two combined will allow me to actually include the pendant of the maji in the suit without dropping below all-70s - and that's just one that is roughtly equal to what you'd get imbuing a regular leather piece to 500% - it could have been 115% intensity higher in just those properties.
So, even just counting 1.0 intensity properties, at max intensity best case scenarios....
1. A runic crafted item in barbed (made initially, or enhanced later using the tool) could be 98 resists (4 +15% resist properties) and 1 property additional.
2. To get the same intensity item from imbuing, you'd have to get +11% in the non-imbued resist while crafting in regular leather, and use the 100% enhancing tool to enhance with barbed. While the total intensity is the same, odds are the only resist equal or better than the runic's will be the one with the +11%, with the other 4 1%-4% lower each.
If the properties aren't 1.0 properties, the potential superiority of the runic items gets even greater.
3. Runic made item - only 2 resist properties, and 3 non-runic properties averaging 1.2 imbuing weight, all at 100%.
15(base)+11(Ex/lore)+12(barbed)+30(runic) = 68 resists, +360% intensity
4. EX leather, enhanced, managing to get all 20 EX bonus points into 3 of the 5 resists (odds of occurring so miniscule it might as well be 0), same properties. Enhanced with tool.
360% intensity non-resists. Resists are 15(base)+20(ex/lore)+12(barbed)+140% intensity in the two 0-added resists (only 16 points!) = 63 resists!
So, in this case, the runic item still is potentially 36.67% higher intensity than the closest equivalent imbued item.
What it comes to is getting something that's got that kind of "wow" power, from the random rolls. But, with barbed kits going on some vendors for substantially under 500k (and it costing about the same to imbue one item with 3-4 properties), it's well worth rolling the dice at the BEGINNING of the suit creation process to try for 1, maybe even 2, high-end items to go with your chosen artifacts, to then imbue the rest of your suit around.
Heck, one of my characters ended up with a couple such items for their suit, and ended up with their only imbued items being jewelry.
