To be fair I haven’t spent a ton of time trying to get runebinder to work well, but on a full pierce conversion infil and then with elemental focus vindicator, it wasn’t exactly jumping off the page in game. Will keep playing with it but going to be niche I imagine.
That said, even with the useless skill bonuses for pure AA:
Runebinder: 115% x 180% (~2.07), 60 flat, 180% damage bonus including dots and basically 18% AS on weapon
Shard: 110% x 118% (~1.3), 45 flat if you fully convert physical, 120% damage if you’re elemental
Savagery 26/16 (ignoring nodes): 115% x 158% (~1.82), 100 flat + 333 dot, 150% damage. Then a butt load more stats if two hander and the following nodes
Shard also loses on QoL with only 1.5 second charge time vs 2 for runebinder and savagery/RF. I’m not sure if there is any crossbow or pistol combo available that’s going to give the flexibility to make up that damage difference, at least not as a pure AA, but maybe that’s the design goal that you flesh out another damage skill as well (obviously the case for runebinder set).
Interested in how the mage hunter turns out. The other piece of this with runebinder/shared is that I’ve had poor results on the majority of pure elemental builds I’ve tried without at least having double RR along with the hyper damage proc devo focus you’re trying. Hopefully seeker+seru+aetherfire are enough to push it over.
edit:
for giggles, looking at the flat on your magehunter with nar’s + shard vs runebinder. Attack speed is basically a wash once charges start
current: ~16,800 across fire/light/cold X 1.3 for shard for 21,840
runebinder: ~17,500 across fire/light/cold X 2.07 for 36,225
That’s a 66% jump going to runebinder. Obviously more to it from other skills and losing +2 all effectively, but…I don’t see +2 all getting you 66% more damage.
Apologies if I’ve oversimplified this, @tqFan should be able to correct my shit if I’m doing this wrong.
