I was a raider once, and had the zeta weapon which was the equivalent Ilvl of the highest ilvl raid weapon. It did not take away anything except help me beat it.

The suggestion was to have the Eurekan Weapons have the same Ilvl as the Raid weapons, but the requirements to attain it will be so insane, that the raid weapon is actually easier to obtain.

They can then later ease the requirements in later patches.

When Pagos was released, I was only able to get 1 Pagos weapon completed before the new patch showed up with ilvl380 weapons. Making it pointless to even go to Pagos lol. That Pagos weapon I made, was only used for 2 weeks. It's not even a good glamour item.
