TBH, I never even noticed the negative stride. My PC was always out in front, so mobility wasn’t much of an issue.
Snake’s Reflexes isn’t a bad way to go, but if you’re going Unbroken, then you’re definitely taking Weapon and Shield Style, right? That will give you a pretty healthy reflex boost.

Most definitely, I will. Right now, in PoE 1, I had taken Weapon and Shield style with a large shield. Reflex went through the roof, it seemed. Overall, I feel real good about it. I think I will have Pale Elf (elemental resistance) or Coastal Aumaua (strength affliction resistance). Man, I'm so excited!
