It was already on my shortlist for the next round of classleads, so my solutions in progress are
Solution 1: Increase faith cost to at least 60%, giving 1 use per faith bar normally and two with the ritual arti*. Solution 2: Mimic the new Aura ritual with recurring reflections instead of a reflection dump, at a faster speed given the difference between a reflection and a shield. Solution 3: Reduce and randomize the number of reflections to something like 2-5.
2 is probably my favorite solution path, since the reflection stack makes things weird.
* I'm assuming it reduces faith cost? It only said belief explicitly last I looked, and I don't know anyone with it offhand.
By the time the leyline hits 50% and alerts you, you have <10s to get there before you're below the hill, and not much longer before they just get it to 100 and leave. I think the one time I've gotten to an influencer is when Lost Forest switched and I moradeim focused to Curran instantly on a good guess. You'd have to camp them to get active fights.
We had some blunders (Mirela missing mass and getting delivered, not blocking when we hit the turn and eating a couple deaths to vortex). Losing one with that many still left us with a huge number advantage, and we were at ~12m in when the vortex SNAFU happened. That's 3m down the toughest part of the line before the debuff weakens.
