So... Relic weapons stuck at lv 115 and new lv120 weapons are coming?

Well, the point OP is trying to make is that you won't need to run any end game to build enough poetic currency to get your i120 weapon. It would only take a couple of weeks of capping it.

You can only get the tomestone to acquire the weapon with Poetics via FCoB. So that weapon will be purely obtainable by raiders until 2.5 or whenever.
