You could also have equipment at below 50% durability (or something similar) be somewhat reduced in effectiveness. This would both make logical sense, and address Gyson's concern above. I think the overall result would be a huge improvement over the current system, and sensible enough to be accessible to all players. To summarize the basic idea:

Repair 1 (equipment below 50% durability suffers reduced damage/armor rating, but there is never a permanent reduction in a piece of equipment's maximum durability):
- Tier 1 Equipment (non-magical) is repaired to 60% Durability
- Tier 2 Equipment (Magical) is repaired to 40% Durability
- Tier 3 Equipment (Rare) is repaired to 33% Durability
- Tier 4 Equipment (Legendary) is repaired to 20% Durability
- Tier 5 Equipment (Super-Awesome) is repaired to 10% Durability
.................................................
Repair 5 (at this level, in addition to the below durability enhancements, all repaired equipment receives a slight boost in damage/armor rating):
- Tier 1 Equipment (non-magical) is repaired to 150% Durability
- Tier 2 Equipment (Magical) is repaired to 130% Durability
- Tier 3 Equipment (Rare) is repaired to 100% Durability
- Tier 4 Equipment (Legendary) is repaired to 100% Durability
- Tier 5 Equipment (Super-Awesome) is repaired to 100% Durability
