This happened on the day PvP came out. I swapped over from healer to ninja and was practicing in casual mode. Overall, I thought I was doing decently well. I figure this would be great time to try out a quick match to see how I hold up in ranked.

A quick match, I say. Boy, was I wrong.

The enemy team had so much teamwork in delaying us, but it was very difficult for us to get a proper group victory. The enemy team was purifying and shielding pre-emptively it was tough to deal any permanent damage. I thought I signed up for the wrong ranked match. We went into overtime without the crystal capturing a checkpoint and stayed into overtime for the longest time. My first couple of attempts to LB got shut down easily, and the enemy WAR was putting some huge pressure to our team by hitting everyone and stunning them each time. The enemy was prioritized in destroying our healer. We prioritized the Black mage. They were constantly able to put us on the defensive, with them slowly pushing towards our checkpoint.

The moment Overtime was called out, we nearly lost when the enemy started capturing our first checkpoint. By this time, most of our team started dying left and right after a good coordinated burst, killing both the healer and the other 2 DPS. In exchange, we only got their tank. Our tank was still running back from respawn point from the last fight. Then, the opposing team started capturing.
1 DPS left vs 4 DPS to stop a capture.

"Good match," said a party member using Quick actions.
"Good match," another replied.

Everyone resigned for the loss. I did too, but I didn't want to accept this kind of ending. The loss, where I felt utterly useless... but I was still alive. There must have been something I could do. I must at least try. I eyed the opponent's HP bars and my own, and then realized I found a chance.

At that time, the opponents dropped their guard and were all thinking they already won and neglected to heal themselves with potions while they were at 70 to 80% HP.
But, they seemed to be forgetting something. They're out of MP to use Recuperation, and my limit break was nearly full. The opportunity was there, but I had only one shot at it.

I immediately stealthed in, assassinate the black mage to bring him to critical HP, and begin my burst. In that moment, I was able to burst the enemy down with my Limit break and stun, successively taking down an enemy while resetting my limit break. The enemy tried to counter with their Crowd control skills and burst my HP down, but I already planned on shielded the incoming attacks and negated the CC effects with Guard. After that, it was a war of attrition. I burnt through all my MP on recuperation and able to get 2 more enemies low enough to incapacitate them with my limit break. I took down 3 enemies, and was on my last 10% HP with no MP remaining. At this point, our tank got enough time to rejoin the fight on the capture point. It was then when our team realized we still had a chance at victory. A very small chance at that, since the enemies rarely died and our respawn timers are much longer, but it was still a chance.

After that was a tough 10 minutes of combat.
And in that time, I began to improve. I realized some flaws with the enemy team, and how I can use those flaws to my advantage. Our teamwork gotten better and better during overtime.

And I was not the only one. Everyone in the party became more motivated to win and began to play better and better. We reacted faster and faster to the enemy team. Our coordinated burst got sharper with each fight. I found more and more opportunities to deliver killing blows.

Even then, they managed to stop us consistently from capturing the crystal with their teamwork, barely allowing us to make any headway. We were consistently interrupted, and there was a bit of a tug of war for the crystal. However, as time wore down, their coordination was beginning to fall off as they started making more panicked mistakes. At some point, it just became an all-out slugfest at the crystal. Our whole team started killing the opposing team more and more often with our healer slowly making the difference in long skirmishes. However, it was a tough match that could go in any team's favor, and we nearly lost again after a big blunder on my end when I got baited to Limit Break at a bad moment and overwhelmingly focused to death. They were completely on guard for my attack and was waiting for that moment. However, our party's overall coordination was too good by then to lose just because one person collapsed in a 4v5. Their respawn timers have gotten too long and staggered. We finally got a win by moving the crystal ever so slightly after capturing it.

That match was fierce. Everyone gave it their all to win and didn't stop. This is so far the longest match I had since the new PvP mode released and I haven't found a match quite similar to it. Everyone could have just called it quits and moved on to the next match. But they didn't.

No one gave up, on both teams. Adapt, Improvise, Overcome. We turned it around. And we won.
