How thorns (dual blader) works

Oh, so thorns only affects people without a base critical? Sounds fair.

I just hope that if we NLs get to fall below the line of DPS classes because of that stuff, we at least get a little boost on training to even it out. Ironing should affect everyone, right? And don't tell me SE make us overpowered. We are average without it, and now things even it out more with thorns.
