Everyone hates Electro Shot, so that needs no introduction why it needs a rework, then while thinking about that rework, Flaming Arrows kinda built out of it separately. (Thanks to @lyric smelt for the final Flaming Arrows idea)
Electro Shot: Bow attack speed increased, rather than projectile speed, and instead of the shitty AOE, Electro Souls with Bow are increased.
Flaming Arrows: Targets hit with arrows get lit on fire for 5 seconds, taking +50% sword damage and +15% bow damage for the duration. Effect doesn't stack, but duration is reapplied if hit with a bow shot while still burning.
