I'm a casual player, I only enter a couple of days each weel to see if there is any new hat worth buying and that's it.
I use the welfare equipment.
This week I've been trying the dual daggers and knuckles since they got an update.
Then I got back to try gunblade for a bit.

WHY THE HELL GUNBLADE STILL DOES SO LITTLE DAMAGE?!

I try every few months because I really like the weapon as a concept, I tried copiying videos with the setup, I got the custom photon arts for ripping regulus to fill the unleased rage skill fast,
I don't think I'm doing anything wrong but it sucks so much.

I picked fighter as I said and I constantly do like 3k dps more and I don't even have a single idea of how to play fighter.
The difference with Hunter and Katana is absolutely crazy but I do not expect to gunblade to reach that level.

But jesus, it sucks so much even with super agressive enemies that allow for lots of counters
