After so much grinding I got elena a couple of days ago, suffice to say she is very good, 2 taunts and 1 with a heal, her heal, unlike lapis which targets allies, its an aoe so you have to be inside to receve it but its kinda stronger than lapis, plus she seems she can hit a bit unlike poor lapis, I was able to reach 2-7, currently im grinding her gear and hopefully I'll reach 2-10 soon.
