The sheer number of 50+ dungeons/raids is enough to help new players along. You can't progress the same as us Day 1ers obviously, but that's a side effect of the vertical progression. Poetics and Soldiery still work the same as Philo and Myth. You can collect Soldiery from every 50+ dungeon + roulettes so ultimately the new player is farming for i100s. In the meantime they're getting clears for each dungeon and likely collecting random dungeon gear as well. Weapons are probably the biggest hurdle since the Sol Weps are the only tome buyable weps and need a UAT so to even get those you need to either build your relic, farm a Primal wep, or buy a wep off the MB of a higher ilevel so you can run ST for the UAT.
