the point is not get a full raid gear, but make relic that at the end can end to be extremely long to get (well not right now the SB one is kinda fast for now, but next step is coming), since for get the last relic of the series, you will need to do many thing and spend a loooot of time into it, then it's normal to ask that this weapon can be at the same level than raid, since, it's only one weapon.

raid still earn different skin, and more powerfull armor and accessory.... then one more weapon that can be chosen for do anything (raid included) is welcome, no?
