I hit 150K Wyrmite on my F2P NOTTE account.
150K Wyrmite, 31 tenfold tickets, 355 single summon tickets, and 3 5* summon tickets means I can do 1915 summons, with 25500 Eldwater from the 3 5* summon tickets since I own a Maribelle.
The stipulation for this account is to basically not spend any Wyrmite or permanent summoning tickets, NO T(ickets or Wyrmi)TE, abbreviated to NOTTE, courtesy of Baladium for the name. Since we've gotten free daily deals and temporary tenfolds, I've gotten 2 5* adventurers, 7 4* adventurers, and 15 3* adventurers from the gacha pool, though I only use story/welfare units. I've managed to get every story/welfare unit a 5* promotion, and everyone but Elias/Luca/Cleo/Felicia have a 5.3 core weapon due to a lack of crimson cores as well as monster mats since 8 out of the 13 free DPS adventurers share the same crafting materials for their weapons (Elisanne, Xuan Zang, Botan, Su Fang, Alex, Melsa, Elias, and Luca).
For dragons, I also only use story/welfare dragons, all of which are level 80/100 aside from the Void Shop Dragons. From free daily deals and temporary tenfolds, I've gotten 5 4* dragons and 11 3* dragons.
In terms of my ability to do content, I'm always able to clear out the Emblem rewards/lotto boxes from raids and the point rewards/trade shop items from facility events. I can clear Master challenge waves, though Nightmare challenge battles are somewhat not feasible at the moment. I choose not to participate in Nightmare Raids since I personally dislike getting carried through stuff. I'm mostly gimped by my dragon options, especially for Water and Light who have yet to get a 30% welfare dragon (Water just has 0 strength options while Light has Jupiter at least).
For Astral Raids I've successfully done Hypnos Master consistently due to it being the strongest welfare-wise with 2 30% strength dragons, 20% strength story dragons, and having 3 DPS Fire adventurers. I haven't done any High Dragon Trials, but my Euden is HMS-ready. I've mostly been waiting on that so that I can use the weekly chests for crimson cores in Prelude (which I can solo), and will probably do HMS attempts once I've gotten everyone their 5.3 core weapons.
For Mercurial Gauntlet, I've cleared level 20 of every Gauntlet and I'm at 27 for Wind, though I've yet to give it another crack since getting S! Estelle and Erasmus. I like to do my attempts near reset so I can try it at my strongest.
For the Halidom, I only have 2 smithwyrms so there's a lot of room for improvement. I have 940 facility levels, and all my event facilities are 30. Gonna be a while before I can max stuff out.
Decided to catalog my progress since we're a little more than a month away from the anniversary, and 150K Wyrmite was a decent enough milestone for me. I technically have a bit more than that with castle/adventurer/dragon story Wyrmite (not including the gacha ones), but I like to save it for when I want to reach a nice round number like 150K.
Going forward, I'm probably never gonna spend my Wyrmite or tickets, but there's a chance I might invest into some of my already pulled stuff once I'm completely finished building my story/welfare units. At that point I'd try to tackle content first only using welfare/story stuff, then attempting with the stuff I've pulled, specifically the gacha dragons since that's my weakest area. We'll cross that bridge when we get to it.
This is a re-post, but I'd like to show this fan art someone made of the welfare raid units pre-Summer again, along with some of the other free unit fan art and one official art since it includes the story units with Alfonse.
Edit: Apparently the twitter artist protected their account, so here's instead fan art of what you should always do with Botan:
