Gunner def weak?

[Lego]

I use folly set and stil,take 300-350 dmg from mobs. Where my braver only takes 200-50. I do something wrong?

Go to My Data -> Character Info and compare their S-Def scores. The gunner's will probably be much lower.

And no, you are not doing anything wrong. Some classes are simply more squishy than others.
