Kinda new player, started back in November. As such, I will try and get, in order of priority:

Nandi
Raid Gacha Tickets
SR Weapons (before the SSRs because these don't require that much materials anyway)
SSR Weapons
Magic Jewels
Soul Points
The other tickets (they tend to be only overcosted R fodder)

But I can see why an older player would only chill and get the Jewels, as the Eidolon and Weapons are underwhelming if one got better stuff from earlier events.
