The corruption Strikethrough (Critical Strike Damage) doesn’t properly work with Storm, Earth, and Fire as the clones do not benefit from the increased damage.
This means that Storm, Earth, and Fire (our main DPS cooldown) yet again actively nerfs and devalues another mechanic due to it’s nature of reducing your personal damage to split it.
What this means is that a 4% Strikethrough corruption is only valued at a 1.8% increase during Storm, Earth, and Fire. Due to it providing a 4% buff to only 45% of your damage.
A problem that keeps happening again and again since it’s inception in legion, and yet another reason on a large growing list why it needs to be axed in Shadowlands.
