Yeah, I think that the epic quality relics that come from raids and champion bags are itemized way too low at the moment. The "rare" quality relic from collecting matrix shards for willpower users is 58 Will, 50 End, and 24 crit, whereas the Rakata power relic averages out to be around 63 power if you use on cooldown 100% of the time (380 power X 20 second uptime / 120 second cooldown). 63 power is not even close to the 58 willpower your get for having the matrix cube relic.
