What should I do now?

4. Start the Relic weapon story line. This will continue and evolve many times over while you are completing everything else listed after this. If you stick it out, you'll have an i135 weapon while will last you in Heavensward from 50 - 58.

Even with the nerfs they made to the quests to make them less grind-y, this is not a realistic goal (especially in 3 weeks for a new player) if his intention is only to get a weapon to hold him over till 60. The only reason he should do this is if he wants to glamour the weapon onto his 60 gear.
