f2poorGODS, let's keep ourselves grounded, shall we?
>Yi Xuan (Ether/Rupture): Evelyn/Yanagi tier, great value as a carry with decent f2p w-engine options in Steel Cushion and the craftable. Highly recommend if you do not have either Zhu Yuan or Vivian. Note that she is NOT Miyabi-tier.
>Ju Fufu: (Fire/Stun): Essentially the Trigger to Yi Xuan's Sanby, top meta if you have them both, but she sees little use outside of that. Keep in mind that rolling for "future carries" has always been discouraged, and that rolling for the support without the carry also doesn't make sense as an f2poor.
>Yuzuha (Physical/Support): Rumored to be a Rupture Support upgrade to Pan Yinhu. If she can be used outside of Rupture and basically "unbrick" off-meta units like Astra does, she is top priority. If she has little use outside of Rupture (or buffing Alice) then skipping her becomes an option.
>Alice (Physical/Rupture [or Attacker]): The only S-rank Physical carry since 1.1. Potentially the highest priority if she is Evelyn/Yanagi tier as well, as her element is rare.
>Orpheus (Fire/Rupture [or Anomaly Hypercarry]): Surprisingly not that high priority due to Evelyn existing. Rupture has proven to be mostly optional, so unless future content makes use of their ability to ignore defense (Miasma is not it), she remains low priority.
Since we have a rule-of-thumb that we can afford guaranteeing 1 character every 3 banners, we are able to choose 2 characters from here. With that said, f2poorGODS should prioritize getting Yi Xuan and Alice (unless she's electric, in which case Yuzuha replaces Alice) first, and maintain a good amount for the 2.x Void Hunter, beyond which we are free to let the penis take the wheel. You're welcome.
