I am fine with Relics being below, until the final patch in an expansion, top raid gear in power.
What I am not fine with, however, is the minuscule power increase that raid weapons have over tomestone weapons.
If a tomestone weapon is i330 upgradable to i340, that upgrade should be made available for everyone at the same time as the tomestone armor and jewelry i330->i340 upgrades. The weapons that drop should be i350, and the Relics between i340 and i350, at the i345 level.
Relics should also come out at the same time that the new raids come out.
That would make Relics relevant, while not overshadowing the raid scene. Also, it would allow raiders something to work on for their alt jobs, something worthwhile, rather than just grinding out another piece of welfare tome weaponry.
