colosus: Simply suggestion. If a char got use set me legendary items on it like a set of elven. Like elven cowl, elven robe and elven boot it must give an special effect on the char wearing it:

Elven set: give 25% on dex and wis.
Beastmaster set: give 25% on endu and health.
Warlord set: 25% on str and damage

futuristic: Nice idea..
