It doesn't have to ignore your level, but your weapon ought to play some part in the calculation of damage (aside from the obvious additional stats on the weapon).

Since you obviously played XI, do you remember how people reacted to relic weapons for BLM? It went something like "LOL THAT'S CRAP". I don't want to see that happen again.

As soon as elemental staves were added to XI, nobody cared about any higher-level weapons for mages. I don't want to see that happen again.
