Unfortunately, you have failed your trial.
You did a lot of things wrong. I am going to say specifically what you did wrong, then I am going to say what you need to improve on generally before you acquire Keyer rank.
At the beginning of the map, it was pretty clear the GT should have been going west, especially so because west was a farming door (and you were the only one with a decent farming level). Situations where the map could go either way, but one of the ways is above other rooms will almost always result in the other way spreading to map, regardless of how the two paths look objectively.
A minor thing you did is you tend to attack melee NPCs first. Attack melees last so you can lure them to the door.
As you were spreeing the crit path north, you never assigned anyone east. In this situation, although it didn't affect the floor luckily, lots of times if no-one is assigned, someone without a free gate ends up doing it, and then they have to break or run it if they're going to die. Luckily I picked up a buffet of food, so I did it pretty easily, but this will not always be the case. Make sure you're assigning every path. Even if there isn't a free gate, you need to be aware and make the best plan you can.
You also assigned Farotto as PT when he was clearly doing another path south (the str door) and there were like 2 other free gates. If Farotto hit a big GD south, and then PT turned out to be map, then a lot of time would have been wasted having to run PT from SW. Luckily Burstz could cover it.
You didn't drop the GT right away at YP, even though the only place the gt could have gone is BS. You ran to the key and then dropped it. Drop it first and then run to the key. In fact, you shouldn't have been carrying the Gt at all since you were FG. P.S: that has happened a lot, where you to run for the key not the enter door. The keyer needs to run for the enter door and a teammate for the key.
Also, if took you like 25 seconds to realize we had YPk and I had to prompt you.
What you need to improve on is map awareness. To be a Keyer rank you " must know who is free gate and who is not". A bunch of times you said "gt fg", which shows that you didn't actually know who was FG. Never say gt fg, always try to be aware of who is fg and who isn't. If you're unsure say "[insert name here] wyg".
You need to direct the team and organize the map better. Do some more keying, become comfortable with organizing the team. Maybe takes some noobs, so that you'll have to think of everything.
Try to think of gates in terms of paths, not areas. I see this lots of times where people will assign someone two gates, which will spree in completely different ways, and make the person really split. You did this a couple times, but it didn't matter because the gates denked.
You need to take the initiative more. Don't be afraid of making a clear and imperative call; it's better than maybes or nothing. Even if you fuck up, at least you fucked up by doing something,r rather than through negligence.
Also you need to improve your attitude before getting this rank.
You may not be re-trialed for 1 week.
Good luck!
