The difficulty curve in the game has... problems...

[Inanegrain]

As I stepped into savage late into the tier, with only experience of EX content, I got trashed, I did manage to clear, but I was bad, I only managed to clear 2/4 floors before the next tier came out, the final tier of the patch.

Then came the next tier, I painfully managed to do the first two floors and the third walled me off for a bit, till I barely cleared it on week 2, on a monday (?) before being walled off by the last tier for over 8 weeks that passed. During the walled off period, I kept looking up guides on how to maintain uptime as much as possible, I kept trying to be greedier, I wanted to cast as much a possible, how far I can push it without dying horribly to a mechanic.

It was hard, I definitely didn't do well on my first few clears, but that improved over time as I recleared them. The EX content... became a lot more easier when in BiS it's subjective, but I somewhat understood how these mechanics worked and slowly it started to feel like a normal thing.

EX content, isn't as hard as savage, but it's still ledge over the climb to savage. If it's your first tier that's late into the tier, you'll probably need to climb steadily for the next tier.

There is no curve, it's more of a 90 degree angle.

Everything in the game can be done by playing with your feet, and then you hit savage and it's not even the same game anymore

This is kind of accurate.
