The damage variance between a Critical Hit and a Non-Critical hit.

This is why we lose stuff like Kaiten and skills become boring auto-crits...

No you lose stuff like Kaiten because the average player doesn't know how to press their buttons and that reflects in the data SQE collects.

Kaiten was a good skill and gave the job some depth, but that depth of knowing when to use Kaiten was too hard for the average player.
