Level 7 Helix, that’s too late. No time to “change” tactics or anything that late in the game. All it can do at that point is allow you to spam nullify/shadow pillar a bit more before maybe having to take cover.
That said, I wasn’t commenting specifically on her squishy-ness but the fact that she seems 1-dimensional and the Helix, at least in my honest opinion, doesn’t really change much of how she is played regardless of which Helix option you choose.
Both Nullify and Shadow Pillar are the main focus of Orendi and she seems to focus on spamming both as much as possible…but at the base both those abilities are just medium-ranged damage skills. I can’t see how I can change up my strategy/tactics with her when she’s just so straight forward…
It’s sad though, Orendi was the character that got me to take a closer look at this Battleborn.
