Favouritre Heroes you wanted but never got?

Fallen Hardin, Summer Corrin, Siegbert, Alm and Innes.

Alm. I didn't even bother with the Falchion Banner since every focus on it was the same color.

Leo is forever avoiding me even though I married him in all my Fates files
Ehpraim is another fave who hates to come home

Dorcas. The main man from blazing blade avoids me like the plague.

Lute.... I want her so bad. I was so scared to summon on her default banner because I got two Mia's on my first roll and that type of luck is usually followed by bad luck for me... I regret so much.

Spring Lucina. Bunny Waifu won't hop on home to truly finish Lucy Emblem

Really wanted Katarina when she was released, but I’ve gotten over it. Probably gonna go crazy for Leif when he comes out tho

Christmas Tharja. I had so many red pitybreakers on a previous banner that I just wanted to take a break from getting yet another 5* Cain, so I didn't even try for Tharja. My #1 FEH regret...

Hector
I'm a f2p player and trying to get him since I started playing, I even got a non-focus fallen Robin trying to summon him (no complaints).

5☆ exclusives are the only ones I don't have Q ^ Q

But I would have to say:
Spring and New Year's Camilla
Summer Corrin
Spring Catria
Hector (either one)
Minerva
Rhajat
Grima
Normal/Brave Lyn.. (I went Lucina for my free pick)
Halloween Sakura
Spring Kagero
Performing arts Olivia
Either Celica

Well, I had all those units you want. But why Joshua and BK ? Both characters were TT rewards...
But, as a player since day one, I never pull a normal Hector (only one LA Hector), and I love Lute from FE SS but never pulled her too.

S!Leo, NY!Takumi and PA!Inigo... all best boys just refuse to come home.. the only best boys who always come home are Chrom and Robin.. just thinking about those 3 banners makes me cry.. so many orbs.. gone..

Leo's been avoiding me for a while, hopefully I can get him before the refine banner ends, but I'm worried I'm going to get pity broken by Eirika.

I've been after Saber for a while too, I hope he arrives on a banner soon, as far as I know, he hasn't been on any other one apart from the Celica's Army banner.

For seasonals I really want to get Halloween Henry when he's on a Legendary Hero banner since Henry was my favourite Awakening character and they didn't do his normal version justice with his stat distribution.

Innes, Ephraim and lady Morgan

Innes,Ephraim,Lute,Elincia and Mia

Normal: Leon, Delthea, Linde, and Hinoka.

Seasonals: LA Lyn (I was too focused on legendary banner at the time), Halloween Sakura, and Summer Gaius (I know he was on the last legendary banner, but I was too focused on other units to try for him). Summer Corrin was also on my list, but now that I got F!Morgan, I became satisfied enough to do without.

There's a bunch so where to begin.
Ayra and Mia who alongside Fir (who I have had a lot of) make up my 3 favorite swordmasters in the series.
Camus, I missed his GHB and really wish he'd come back because my horse emblem teams have firepower but no real great bulky baiters. In a similar regard Sigurd, maybe that Miracle banner might get him, or even Eldigan. I really do like the cast of FE4 despite having yet to finish it though.
Micaiah, RD is my favorite game and while she may not be my favorite RD character I'd love to have her.
Minerva, the OG wyvern lord and one of my top 5 favorite wyvern lords alongside Jill, Haar, Altena and Miredy (or whatever her official translation name is). And unlike those 4, Minerva is in Heroes currently but I don't have her.

Hector, Alm and... dragon waifu Ninian
