Balance changes
"We observed changes after distribution of Ver and made additional adjustments to slightly lower the fighting power of certain weapons that could hold the battle line from further away.

Also, we made adjustments to narrow the margins by which certain weapons were strengthened in Ver 5.4.0 while also lowering the frequency at which special weapons can be triggered. At the same time, we expanded weapon choice by increasing the abilities of certain weapons that excel at closer ranges.

In addition, we reviewed some of the weapons that previously had their capabilities lowered, and as a result we slightly reverted some of the lowered values and made some adjustments to points required for special weapons.

We will observe the changes after this update and make further adjustments to in the future."
