(Please view in the comment section as it will display a very basic format/drill of Line Dueling, please share that concept around and improve on it!)
So let's face it: Line Duels/Battles are the most exciting thing to do in this game, the downside: Line Battles are only fun if the entire team cooperates. Not only that, Sometimes when facing other classes that can easily mess up your line, Line battles can become fustraiting to conduct.
So I'd like to advocate for something here, let's make Line Battles become something that is very common amongst the community, and not something that should be shamed and shunned at a mere mention of it in-game.
So please, comment on what your opinions are on Line battles! Tactics, Formations, Counters and maneuvers, or just plain comments, whichever you wish!
