How many feathers per week do you all get?

I actually don't count my feathers. (Probably because I don't promote much, so I have 180,000 feathers)
But, I can make a rough estimate.
I hang around Tier 19 in Arena +2,000
AA varies, so I'll say around +1,500
+1605 from Dailies and Logins
That's only 5305 feathers per week, but I haven't counted other things that get you feathers, like Infernal GHBs, VGs, TTs, Chain Challenges, and Blessed Gardens.
Edit: I didn't count Offense and Defense Arena feathers... Whoops.
Defense I don't use bonus units normally, so +500.
Offense is +2500.
That's 8305 Hero Feathers. Sorry for the mistake.

I’m always a little sceptical of anyone that says they get more that 15k a week. I get 10.4k from Tier 20, and AA (top 1000-3000 rank) per week, and this is topped up by quests (100 for Arena, 100 for AA) and any extra quest and stuff (the blessed gardens where great and beating Zephiel on infernal too meant I got some insane amount of feathers this last week and a half)

On a regular week, considering 0 quest feathers, nobody sent home, and just getting daily rewards and being T19.5 and top 10,000 in AA, here’s the math:

T19.5 averages 2,500 feathers per week + another 2,500 for offense + 900 for a 451+ defend, that’s 5,900.
AA top 10,000 gives 2,500 feathers.
Quests from doing the AA consecutive wins and 2 Arena wins combine for 1,400 total feathers.
A bonus gift gives 100 feathers twice during the weekly gift cycle for 200
Conversations give 15 feathers per day for 105 feathers.

Adding that up, 5900+2500+1400+200+105=10,105 feathers per week. The only way that goes higher for a stagnant value is if you become T20 permanently and get higher on AA, which will add 3,000 feathers to that and make it 13,105 per week by just doing the permanent in game content.

Quests can give that a boost, as monthly quests can tack on extra feathers (around 2,000), as can doing lower difficulty CC maps you haven’t done yet (200-400 on normal, 400-800 on hard). Some people pay their way to sending home many units to really boost their feather reserves, as sending 10 5* units home can boost your feather count by 10,000 right there. TT is what really can give you a lot, as the quests alone give close to 10,000, placing high gives you another 10,000, and HM grinding is huge, and can give a few thousand or upwards of 30,000 feathers.

On a down week though, I’m more than ok with a “meager” 10,105 feathers. Lol

6,400 from arena(2,500 offense+ 900 defense+ 3,000 tier 20) + 5,000 from AA(top 1000) + 1,400 from arena/aa daily quests + 105 conversation/greetings , that is already 12,905 feathers. That is not including HM farming when I have nothing spend stam on, I do normal cc 1-2 which gets around 32 HM per run and will take about two weeks to cap from 0, or other misc things like infernal, new modes, other quests, ect.

Average at 9.8k since im in tier 19.5

around 3000, combining both arenas

Here is an interesting thing you can do if you want more feathers. (I didn't realize this until recently. Maybe you already know this, but I didn't)

1. Each time you complete all the chapters of a new story at lunatic level (example book II, Chapter 6) you complete a mission. If you go to the fountain icon and click the glowing icon thing in the upper right part of the screen you can see your fire emblem points. You can collect 100 points for each mission completed. You can then select 2,000 feathers as a reward for each 100 points earned. If you are a new player there are 21 missions to complete. You can buy orbs one time, but if you spend the rest on feathers that's 40,000 feathers for completing the story.
2. If you have your Fire Emblem account linked to your nintendo account you can just login to the Nintendo website once and a while and you'll get nintendo points. You can cash these in for the same feather awards. So 100 points = 2,000 feathers. You have do do this via the Nintendo website, not via the Fire Emblem app. I'm not even sure why I get points sometimes but I've claimed the reward a few times now and I've only been doing it a handful of weeks.
