Seems L2P issue.
This game has clear CC system:
1. CCs that make your character unable to act - mezz, stun.
2. CCs that relocate your character - knockback, push, pull.
3. CCs that alterate your character movement - slow, root.
1-2 build resolve. 3 does not build resolve.
blind either does not give you resolve or it gives very little resolve
blind is in category 1 makes your character unable to act
blind in itself is not dangerous but combine a mezz/blind without counter and a regular stun
