Elemental advantage is a big boon, and will likely impact whether you can reach the 3 and 5 orihalcum tiers. On the flip side, you shouldn't actually NEED the extra 3 orihalcum unless you're running more than 2 elements. 4 orihalcum a month should be plenty to feed teams for 1-2 elements and keep them maxed, and as an added bonus you won't need to bother with the challenge objectives.
