Elemental Resistance: Why Even Have It?

[Magis]

So, there are a couple little things in this game that really bother me, but none quite like elemental resistance.

I can't wrap my head around this concept, it seems so half-baked. Does it have any meaningful impact on anything and if not, why even have it in the game to begin with?

The way I see it, they should either completely do away with it, or make it meaningful, yet with each new primal we get more of it.

The same could also be said about the member of the twelve we chose, or our character's birthday. If choice is to be in the game, make it an actual meaningful choice, not an arbitrary construct.

Has anyone found a practical use for elemental resistance or elemental potions?

I think a lot of it is just carry overs from 1.0.
