Relic isn't just for raiding. It's about the effort to gain something special. A special shiny weapon!

It's more important for glamour then for the stats. Most raiders are loooong done with the raidtier, when the final relic is available.

The old relics are not 'hard' to get. You don't have to do something 'hard'. But you have to put effort into it. And so it feels rewarding in the end. The EW relics feel just meaningless. :/
