Sorry to bump this thread, but I bring some information about your request. Hopefully it will shed some light on where the development team stands.

Currently for ranger, when you’re afflicted with double weakness, ranged attacks will always miss. Since this makes WS miss as well, it’s not possible to exploit weaknesses in VW and other content. Could you please make these misses act as zero damage instead of a pure miss?

Elemental magic is also penalized while under the effects of double weakness, but it does not miss, it only becomes zero damage, thus allowing it to be used to exploit weaknesses in VW.
Could you please look into this?
It’s not that it will always miss, but when you become K.O.ed while under the effects of weakness, your attack accuracy becomes extremely low. The method of determining accuracy for close range attacks and ranged attacks is different, and this effect is more noticeable for ranged attacks where the accuracy floor is much lower.

I believe that your request is asking whether we can increase this floor; however, if we did this, monsters would also need to undergo this change.
*Monsters will never be under the effects of weakness, but think of this as ranged attacks from lower level monsters hitting players with a greater degree of accuracy.

Also, when you are KO’d while weak, limitations are set to lower your contribution to the battle and making adjustments in the direction of negating these limitations is like putting the cart before the horse.

While the thought is to have a penalty and have players be mindful in battle so they don’t get KO’d repeatedly, for the example you gave about Voidwatch, we understand that currently there is a lot of AoE damage and it is easy to get caught up in it and die. For this, we would like to make adjustments to the content itself so as to not create situations where you need to fight while weakened.
