This month HHG updated the crit damage stat to a percentage. Almost all heroes have around 150% crit damage for both normal and elemental damage.
Yet in practice crits never do 150% damage. It seems like only one of the damage types is critting, 10k shots will give 12-13k crits, it also doesn’t compound with other damage bonuses.
HHG really needs to fix this, or at least update the tooltip and explain how crits are actually calculated.
