What should I do? Please help

did you get anything else from the banner? or was it just the 1 5* everytime (just curious there).

I'd cut my losses and try for her when she becomes a focus unit on a L!Banner (maybe she'll be with Lucina).

When I had to blow up tons of orbs for one char I tend to ask myself if I am ready to keep on to get him/her, usually I go to the very end. Not often but I had couple of bad times, when I barely got F! Morgan on her banner on last orbs I had, same goes for first LB for grima, I got up to 10%,wasted every single orb I had but couldn't get her. But anyway, if you have pity rate go on to get something worth while of those orbs you spend.

Look at the banner as if you had never pulled on it, because having spent 220 orbs doesn't actually do anything if you have no pity rate. Don't work by the gambler's fallacy. Would you pull if it was your first orb on the banner, given what other banners are going around?

That really sucks. But she's available at any time (not seasonal), so I'd probably just wait and hope to get her later. I mean, there are some units that have been out since I started playing a few months after launch, and I still haven't managed to pull them, so that is a gamble. Then again, we're not really sure yet which of them is going to demote. I'm hoping it's Silas like everyone says, but "everyone" has been wrong before. You'd probably feel silly spending more to get her and then have her demote, especially if you still don't end up getting her. (I spent a bunch of orbs to get regular Shigure when he came out and got three of him, but none with ideal IVs. I was really happy when he demoted. I've since managed to get one with ideal IVs thanks to that. So I guess if you did manage to get her, even if she demoted you probably wouldn't regret it.)

With a regular character like this, I'd spend less money than I would for a seasonal, but even with seasonals, it's always a risk. I wanted Summer dancer Xander so bad, I spent $320 on that stupid banner and still didn't get him. So many pity breakers.

If you've got FTP orbs to spend, then of course spend them to try to get her if you want her that badly. But if you're talking money, unless you have so much money that you literally wouldn't notice losing a few hundred, maybe hold off. I can tell you from my Summer dancer Xander quest, no matter how badly you want the unit, that doesn't mean it'll appear. Or even that any 5-star will appear. I spent $75 for an extra 140 orbs (after I'd already told myself I was done; I should have stuck to my decision) and even sniping only colorless, not only didn't get him but didn't get a single 5-star unit in all of that.
