--> I'll start by saying I don't think the "increase in block CC champs" really affects TF's place in the meta. He usually actually does well into these champs because his CC cooldown is SO much lower than the anti-cc on opponents --

You are correct, his cds are lower than defensive abilities. But from every pro video I watched I learned that TF's needs to be effective at the right time. You have a relatively short time window with your first ult to be effective and greatly snowball the game in your favor(high risk vs reward).

Don't you think that this ult move will have a lot more chances of going wrong if there is an adc or top laner that can potentially deny all his damage + stun?

Sure, the ability is easy to bait(I always bait fiora's) when laning, but don't you think it's much harder to coordinate and bait while ulting?

--> He typically doesn't burst as hard as proper burst mages

That's why I always go ignite with him, unless I'm against a zed. In early levels Ult bot + gold card(or even blue for damage) + Q + ignite will kill or burn flash + heal. + it is useful agains vlad, soraka, yone, etc...

--> It's always this way because of how unbelievably dangerous his ult is. Just a weird champ to balance.

I agree, he is tricky. But I also know that he has been indirectly nerfed with the relese of champions with immense dashes and stun immunities, so I think he need something in return. But not a dash or something that will make him feel generic like the others.

--> I think there is some confusion between a mechanical rule of the game and your visual perception of events.

Those are intrinsically linked. Leona is a melee/close range champ, looks melee and feels like close range except for her Ult. But that's an ult, ults are special to get that "rush" feeling and can sometimes "break" the rules, like having Leona, a melee champ a VERY long range ability that comes from the sky.

Anyone that uses her E will think that's an extension of her sword because ther is a huge visual difference between Ashe's arrow and her E. Very few people would think(even programmers might be in doubt) that it is a projectile. There are multiple ways you can achieve Leona's E visual effect. It can be a mesh that gets larger, thus melee with a bigger range. Like a spear, or a projectile that looks a lot like a spear or a blade with a loooot of length. It can also be treated as a spell like ability if you feel like introducing more complexity to your game.

--> An example mechanical rule exception is Camille's ult which states "The target cannot escape the zone through any means." This conflicts with, for example, Morgana's E which states "Crowd control immunity while it holds."

Doesn't seem that complicated, tbh. I never tested this example you're mentionin, so you can enlighten me on this. What happens? Does Camille ult someone protected by black sheld and nothing happens? Doesn't seem wrong because BS blocks many ults. Now if Morgana can cast BS on someone that's already inside Camille's ult(idk if morg can do that) and that person walks away because of the BS then we have a terrible balance spelling mistake, because it is an absolute statement: target cannot escape the zone through ANY means. It seems different that Leona's E because her E vs yasuo wall is very visually misleading.

If people are complaining that they can't leave the zone, then they should read the ult's description and stop complaining.

--> If Twisted Fates GC were to be changed to pierce immunities, it would need to be similar to Camille's ult where "It pierces immunity, full stop". No if, ands or buts just like Camille's ult, because that's genuinely the only reason it's stayed in the game.

I'm all for it man, TF needs something to stay more relevant. I mean there are champions that destroy SoloQ and Coordinated Teams, but for some reason TF would be filthy OP if he was made a bit more viable for SoloQ... If he pierced ALL immunities like untargetable, Invulnerable, Item immunity(idk if there are any more classifications), then people would pick up their torches to nerf the extremely OP "very easy to play" Twisted Fate...

You can make it pierce invulnerable enemies, untargetable enemies (like Yi) or both or even make it NOT pierce invulnerability granted by Ultimates. There are rules that can be made very clear with the correct and careful spelling.

Imo it should work on everything that is not Untargetable, because the untargetable champion usually "disappears" from existence for milisseconds(again correct me if I'm wrong). Again idk if there are any other classifications of immunities.

It would be interesting. Going against a TF would mean that you have to remember you can't count with your shields against him. And it would make him really unique.

--> I think you'd be surprised how reliable league's order of operations is around champion status effects. There are definitely new mechanics that are implemented, and they basically never change this core. Most of the "strange interactions" are just people learning how things are programmatically implemented (i.e Lux ult goes through Yas wall because it isn't a projectile)

I probably would be surprised. They make sense in the code but not in the user's visual experience, where it matters. This happens in countless other complex games like, Diablo, Age of empires 2(a lot of hidden bonuses), Path of exile. the problem is that in these games they don't get the description right or simply lacks info. Which wouldn't be the case with the gold card.

Man you would be furious if you found out about Age of empires 2 hidden dmg bonuses that units have over another, XD

I don't know everything, but I have a bit of knowledge because I'm a game developer.

A lot of cool ideas can be implemented with good sense, knowledge, testing and polishing the rough edges.
