Thansk for the feedback.
There was a localization problem where the "Soldier" name was not implemented correctly.
It displayed "Regular" instead for every melee warrior.
This is fixed on our side, and will be up-to-date with the next fix.
This is only a text display error - the Crâne Warrior, the Knight of the Lion or the Blood Predator / Grave Guardian are still considered Elite for all gameplay effects (such as spells, etc).
