The way Chain Reaction works is if Unchained deals the killing blow to a burning enemy they have a chance to explode. It doesn’t matter who or what ignited the enemy, as long as Unchained deals the killing blow to a still-ignited enemy.
These are probably the two biggest ones. The chance to proc was actually made pretty high. 40%. But it doesn’t really matter because the talent itself is so underwhelming. Patch 3.1:
Searing grasp was changed into:
and Flame Wave into:
The above two changes were likely made in an effort to make Enfeebling Flames (and lesser extent, Chain Reaction) easier to proc, but “Outburst” is still terrible in general. Probably wouldn’t be as bad if she had a shield weapon.
If Chain Reaction did damage, ignited enemies at all (currently does not) for a meaningful duration, had meaningful stagger, or did much of anything really, then it’d be worth something. Some thoughts:
- Give it damage on explosion.
- Have it apply a lengthy burn (E.G. 5 seconds).
- Apply stacks of stagger to enemies for a duration longer than their animation (E.G. 5 seconds).
- Lower their mass.
- Slow enemies down.
And remember that the talent itself doesn’t necessarily need to remain in the game as is. It could be reworked entirely into something else.
