Quote from Rynn;1291270:
As for ER vs ele, it's personal preference.
Nowadays it seems most efficient to ditch ele entirely and go for ER on your bow for added dps/versatility and just use ninja/gun/magic/final hit against all the older content that isn't ele immune. Or if you have lots of gold, make one ele and one ER.
Probably the factor to consider while choosing the weapons in my opinion.
To add in to the discussion, I know it might not be the answer you want for your question, but I want to say, why not both?
I have been using my Bhafel Combo with ER and CRC with elemental reforge. My reasoning is that for CRC, in contents like Alban, where the slight refire animation as well as the farther range is important, as well as fire arrows, basically falls behind compared to Bhafel Combos. In all honestly, I would rather be using Salvation Bow rather than CRC in Alban. If you're like me, you can use CRC for contents like daily missions and MA.
Since the above already mentioned the pros of each side, I'll mention the cons here.
Bhafel Combo:
-Needs two pieces to be powerful. I mean, CRC needs the sharp bolts too, but those are 10000x easier to get/buy.
-Each pieces already cost a fuck ton more than the CRC.
-Roll dependent.
-Slightly less damage in higher prot mobs (but not too significant), but thankfully covered by the pros of the weapon
CRC:
-Not as expensive, but radiant strings are pain in the ass to get. I've honestly had better time gathering dragon scale fragments than these strings.
-If you're dumb with upgrading, you get less than 80% balance.
-Shorter range.
-Harder to aim because of shorter range, and also harder to know when to shoot because it doesn't have as visible motion as bows do
-Bolts can theoretically run out, though this shouldn't be the case because we know how many people sell out the bolts they get from gachas really cheap.
And if you want to maximize your damage against foxed or barrier spikes, Bhafel Combo is still the way to go.
Also, not sure if Salvation Bow was in your consideration, but worth noting that Engineered/Magic Crafted weapons can have a hilarious bug of having double the crafting bonus, demonstrated by this Salvation Bow:

My favorite part of that bow is the max and 41 dura.
