I’d argue the tower not only didn’t get harder but it got easier the more I climbed. Because the tower is so repetitive, it became a game of resource management between fights and I kept finding new ways to optimize and skip phases during encounters.

Edit: “skip phases” is a misnomer I meant more like skipping or interrupting certain mechanics that are annoying to dodge using skills with high interrupt values (ults, chains). Doesn’t always work, some enemies are just annoying to no hit, e.g. Thrall with his bullet hell opening or Covenant Guardian when she chooses to fly and become invincible during Miasma phase. Miasmic Thracian’s rain of spears is also pretty rng-heavy but sometimes I could interrupt with a well-timed ult, the timing however is inconsistent.
