I will literally take Lee, Elise, Zac, Sejuani, and Rek'Sai

Yeah but it's mostly about buffering your abilities once you've learned his essentials like the ones you listed.

Beyond that, just try not to fuck up your E+Q combo as it is bugged since release, unfortunately.

The problem with this is that Kindred isn't a spellcaster, she's an auto attacker. Also Mounting Dread is 2/3 Lamb, wolf only applying the execute after 3 autos and initial slow

First: I think you have a pretty good interpretation of Kindred and I admire that you like them how they are.

How I see them: Kindred are a personification of the Yin and Yang thematic, both visually and philosophical. They always represent clear opposites. Wolf is the male part, Lamb the female. Wolf hunts down these who run away from death, Lamb gives peace to these embracing her.

I would say many players see the Yin and Yang thematic in Kindred but more superficial than you do. You have a deeper and better interpretation than most others.

However it feels like the execution of the uncontrollable wolf and the calculating lamb could have be done better. With the current execution it feels like wolf isn´t important.

Why does it feel like wolf is unimportant? Because everything lamb does has some significant impact on the champion.

Lamb has:

Has control over the health bar/ only her hitbox counts - If a skillshot hits lamb Kindred gets stunned or loses health. Wolf has no hitbox. Your enemies never aim for wolf never click on wolf to autoattack Kindred, which contributes significantly to the Kindred is the lamb thinking most players currently have.

Movement command - It´s the most basic command but also the most impactful command. You use it 24/7 in LoL (except you are post 6 urf Kassadin). And while it´s something we don´t really think about, it is a significant part of a character.

Why is it lamb exclusive? Because lamb does something, if you use it you see lamb walking through the rift while wolf is some addition which tries to stay close to Kindred.

Autoattack command - Similar too the movement command. It´s one of the basic things which is impactful (especially when your champ relies on them) and which you use 24/7 as an ADC (like Kazekiba mentioned Kindred isn´t a spellcaster). It´s like the movement command a significant part of a character.

Passive - With which you actively choose a champion,

Q - Is a mobility spell (not just a movement speed buff but a dash). If you use it right you can survive dangerous situations or get a kill, if you use it wrong it can lead to your death. The dash feels gameplay wise and animation wise really impactful.

R - Has the potential to warp entire teamfights. You can save allies, enemies and neutral units from death. It´s pretty impactful gameplay wise. Not to mention that ultimates are normally the "special" part about a character which is quite important and get some additional attention.

Wolf has:

Passive - With which you can´t actively do something. You interact with it but you spend less time thinking about it as if you do when you mark a champion.

W - Does some additional damage and enhances Q. Which leads to Lamb using her Q more often; which leads to Lamb getting attention/recognition while wolf actively does something. Also lamb has still the spotlight because you move with her.

E - Lamb does 2 autoattacks and then wolf has finally one attack which again does a bit additional damage. (Damage is impactful but compared to a stun or a dash I would say it feels less impactful, especially when you already do a good amount of damage through your autoattacks.)

I find the idea of Kindred interesting. But I can´t stand her gameplay. It feels gimmicky/unhealthy (hunt mechanic) and lackluster. Kindred has some potential but they didn´t really use it, that´s what I´m disappointed about the most.

And about the thing that a Grim Reaper shouldn't save someone from dying: There are actually quite some tales in folklore, in which the Grim Reaper decided against taking someones life, because it "isn't their time yet" or other reasons.

The Grim Reaper decided to not take someones life. The grim reaper didn´t actively saved someone but recognized it wasn´t the persons time to die and did nothing because of it. The Reaper didn´t took the person with him nor did he save him. He just left the person alone and waited until it really was the persons time to die.

That´s what I understand from what you´re saying. However I don´t know the folklore and can´t read it for myself to better understand if the reaper simply recognized it wasn´t time for the person to die and did nothing until it was time for the person to die or if the reaper actively saved the person from dying.
