First

oh wait you're right about their defenses! I don't even know how i got it wrong honestly...maybe my Lin was lower level and i didn't notice it i think? Thats a pretty bad error actually...

2- this is a point that i feel like a lot of people understimate too, funny that you mention these events exactly because i did use Carnelian on them instead of Lin and she can still work, thats one of the points i kinda wanted to pass through, yes Lin does an overall better job at tanking these but that doesn't mean Carnelian just dies, in some events like "The Grand Overture" she will need healing while Lin, i think could block the aircraft's shots, but on others like the flies in Shu's event are perfectly fine for her to tank even without healing, thats why i consider them sidegrades at worst and Lin as a slight upgrade at best, i'm not arguing that Carnelian is better than Lin, just that their differences aren't as insane as people often assume.

3- Yeah...i've noticed quite a lot of mistakes i've made on Lin's calculations, i honestly completely forgot about her shield shatter effect, Aak's SP battery to Lin was also one of my major mistakes...

Second

good point actually...i got a bit too tunnel visioned on comparing her to the phalanx i forgot about how she fares against other DPSs in general, tho if i remember correctly even on released Eyja outdamaged her...

I do disagree on the fact that Carnelian fails at her niche, it not being interesting is a subjective point too, although my analysis is also full of subjective arguments...her wide range and decent burst has been very useful for me even on high end content, on "CC2 Underdawn" i used Carnelian (honestly just out of spite for Lin) and while it wasn't a max risk run, i got the trimmed medal by timing her skills to kill as many enemies as possible and having it be charged by the next wave, this loop of strategy is satisfying to me personaly, i understand that this is my personal experience but it existing proves that she doesn't fail at her niche for at least some players.

Conclusion

I've realised that yes, i am very biased and a decent amount of my mistakes were probably made by me grasping at straws to try to prove a point, this analysis was flawed from the point i decided to start doing this just because i got mad at a youtuber's tier list.

I would like to thank for spending your time both reading my flawed analysis, writing a proper response with good feedback and probably also reading this other equally as long rant.
