Moderate Relationship between random DC and Warrior Final Attack

hello
Recently, I have been experiencing frequent 'random dc in 5 min' issues since last patch.

While looking for a solution to the problem on the forum, I found the following article:https://royals.ms/forum/threads/unable-to-connect-to-the-game-server-constantly-random-dc.220767/

In that article, he claimed that dc problem disappeared when final attack was turned off.

I also followed that solution and that problem didn't show up.

 

I got the same Issue and I've had this problem for at least 2 weeks
