Why make characters obtainable 5* and 4* to 4* and 3*?

I think that it's better in general for the following reasons:

1. A lot of units that were demoted have no business being in the 5-Star pool. Notable examples include Merric and Jakob. This means that you cannot be pity-broken by them any longer.

2. A lot of top / high tier units are now easier to summon and build up to 5-Star Lv. 40+10, such as Nowi, Fae, Reinhardt, Lukas, Leon, Marth, Eirika, etc.

3. Some really nice fodder is now more readily available. The best fodder in the game--Klein, in my opinion--is now available in the 3-4 Star pool, which is absolutely insane to think about!

I take it you've never gotten a 5* merric or peri at high pity %?

This definitely makes things better. The 5* pool has become a little less bloated and far more units are available for fodder. The next step for IS is to demote the unworthy 5* (mist, saber etc) down to 4*.

Then summoning will be a wholesome gambling experience.

Because people got tired of getting useless 5* units for pity breakers.

THESE units are the units that made people HIGHLY upset because they reset pity percentages.

Although I'm surprised they took Reinhardt out of the 5* Obtainable window.

I'm happy they've done what they did, I'm still looking for a Marth and better IV Fae, Nowi and Corrin which I now have more chance of getting. What I'm annoyed about is they left all 5* exclusive heroes as was, this was the time for those who've been in the game since the beginning to at least be available at 4* but sadly no, no 4* Lucina to let me merge her.

Thats why BHB Summons would fulfill that role for the demoted 5*s? Needs Hector to be a 1* Unit XD

I had the same issue when someone proposed IS to do this a while back - he said Caeda doesnt deserve to be in the 5* pool, and should be demoted. While I am a great fan of Caeda and wouldn't mind getting pity broken by her at all if it means I can easily get merges for her without using precious feathers.

However, this is a necessary step. If you are a F2P player, then you will quickly hit the end of the road in Arena, as you need highly merges units to compete in the highest tiers. For a F2P, it's just not possible to +10 merge any 5* exclusive unit that comes out, and most of the time only the weakest unit gets demoted to 4*. If you wanted to compete, you were basically forced to use units available at 3* and get them to +10, maybe one or two 4* units that you were lucky to get often enough ( I had been visited by an odd amount of Titanias and Sorens, for example). And IS NEVER Added a new unit to the 3* pool, meaning you are stuck with extremely few units, who are often tremendously weaker than any new unit coming out.
This holds true for skills, too. I don't like wasting a rare unit just to give away their skill, so you are stuck using weak skills that earn little score in arena. It just sucked big time. You are basically forced to work with only 10% of the assets of this game, and that is the weakest 10% mostly. Now that has increased to 20% at least. Seeing the demoted units, it's still the weakest 20%, but hey a small improvement is still an improvement.

May I remind everyone that they can still be obtained as 5* when their banner rotation comes up. At the very least trying to get focus units has become much more manageable with these ex-5* units out of the way. Getting a 5* unit should be an exciting experience, not a depressing pitybreaker. Friggin Ogma and Cain for example. Barring brave sword, their useful skills are available at 4*. And we have Luke who is also a brave sword unit but at least has a premium Panic Ploy skill that justifies his 5* status. Even if this was the only update, I'd be just as glad as I am with the whole package reveal.

I am very happy with this :) Ogma just broke a summoning session and Peri did twice already.

best Thing imo is Cordelia and Chrom hrhr
1. looking for a galeforce fodder for a looooooong time and will make heavy seals builds much more often (I am considering a Sothe Peshkatze sweeper as soon as I finally get that skill)
2. Aether builds incoming

Spoken like someone who has yet to feel the bitterness of being pity broken.

20k is a pretty cheap investment nowadays if you complete your arena rounds and quests every week.

On the other hand, losing a potential 5-6% pull rate on a shit character that serves no purpose other than rotting in your barracks or fodder off if you're lucky and losing your likelihood of pulling a focus character is a much bigger frustration than choosing to use 20k on something that you can freely choose to invest in.

tl;dr - to put it mildly, pity breakers can get fucked for all I care and bless IS for this update
