Artian bow question

So the thunder bows in the game are noooot quite up to my preferences for a few reasons (coating, built in skills). I understand artian bows are random with what coatings they can use and I did fiddle around with one for a bit. My question now is, if I make an artian bow and this thing rolls more elemental than anything, sitting at 190 base raw at rarity 8, is that desirable? Or is that too low raw? I know we want to absolutely blast affinity through the roof for crit element but how high do we want to go with elemental damage?
