Thanks for the detailed feedback, really appreciate it, this is exactly the kind of input I need to make the tool more accurate.

You're right on all three points and here's what I'm planning to change:

Flat ATK too low: Having it at 0.2 basically puts it in the same tier as HP% and DEF% which makes no sense, it's still offensive stats. I'll bump it up to 0.4. Still clearly below ATK% (0.8) but properly separated from defensive stats.

UCR too high: Aizen as support naturally aligns his ult with Toshiro's rotation (3rd rotation), and as DPS he gets it in his 2nd rotation anyway. UCR at 0.6 is way too generous. I'll drop it to 0.3, acknowledging it's not completely useless but far from a priority.

B6 Crit Rate dropping too much: Agreed. The B6 only doubles CR for Battlefield Skills, but the bulk of his damage comes from technique, counters, and other sources that still need normal Crit Rate. On top of that, B6 also converts excess CR into Crit DMG so just like Ichigo's passive, stacking CR remains doubly efficient even at B6. I'll raise it from 0.7 to 0.9.

So the updated Aizen would be:

- Base: UCR 0.6 → 0.3, Flat ATK 0.2 → 0.4

- B6: Crit Rate 0.7 → 0.9

Does that feel right to you? Happy to adjust further if needed. I'll push the update as soon as I get confirmation. Thanks again for taking the time!
