Level 93 LL MoM Crit Firestorm of Meteors Elementalist^3.27

Notes

This build seems to have several weaknesses at first glance:

1. Dies to Damage over Time easily
2. Delayed damage output: needs to apply ailments via a critical strike with Wave of Conviction before all our damage ramping comes into effect.
3. Our critical strike chance is only around 50% when first engaging the enemy, delaying our damage output further.
4. Wave of Conviction can only have one at a time, so you can't use Unleash Support with it very well.
5. Because the initial damage is low, the ailments are weak, so they do not provide as much strength to us as we would like (e.g. not high Scorch to reduce resistances and not high Brittle to increase our critical strike chance for Firestorm).

However, the build does fulfill its initial theory: when it is prepped correctly, the meteors are very powerful. But they are inconsistent and delayed, and since we are weak to Damage over Time, this oft proves fatal.

Experience fighting the Maven confirms this: projectiles were tanked without issue, while the damage over time pools were near instant death.
Likewise, we struggled with damage whenever we did not crit, but when we did, we nearly one-shot the phase.
Improving consistency in critical strikes is our first priority for improvement. I don't know whether we can realistically solve the damage over time problem, so we may need similar treatment with this build as with the Bloodfiend build:
DoT mitigation in the form of getting "Unaffected by Burning Ground," immunity/avoidance for Bleeding, Corrupted Blood, and Poision, and avoiding encounters that have damage over time/learning to dodge said abilities consistently.

The current build cost around 12 Divines to fully fund, so it is fairly cheap, though you have to switch to it (perhaps a league starter version can be made some other time, if this endgame version can be improved).
Perhaps improvements could be made with a higher budget and more time to rectify some of the above issues.
