at first sight I was about to say to reroll the LoH for %dmg (6-10), then I noticed that the dmg rolled minimum stat (I think the bare minimum is 869 and you rolled 870). So my advice is to roll the dmg, if you manage to get a value toward the higher stat (the min-max damages roll accordingly, so if you roll max on one you also roll max on the other and vice versa) will be a bit higher base dmg than with a flat %increase on a low value.Need help on what to re-roll on my first danetta's piece.
From what I understand it's on the bottom end for damage but since it rolled with a socket to begin with (maybe all of them do?) I have a few options.
Anyway it's not a big difference between 10% dmg increase and max rolled dmg (on favor of the latter), so it's your choice, just remember that if you decide to reroll the LoH for %dmg you'll lose it, if you reroll the base dmg you'll keep it and even if it's not the most desirable stat it's still better having it than not.
I'd reroll the base dmg
