And you know what players that also raid do have Relic weapons as well (some do).
You fail to see that some players like the grind that comes with Relic, no reason it should not be "Powerful" like it currently is.
And what about the tome weapons? This does not really require any skills at all really...
Not everyone has time or could be part of or find groups to raid, Relic is a different path is all.
Only thing i would say is certain parts of it should have some sort of Challenge like the Relic back in the day having to defeat Primals in sub 90 gear
