Quest almost had it.
If Ammar did just focused on their objective to just destroy the T3 tower, it would have ended well for them. But Team Liquid did a come back, gg and well played for both teams.
Ammar is a double edge sword player, He is good when he is on the zone but he is bad too when the game is not favoring on his team. He is easy to become carried away on clash and become arrogant just because his hero has an early advantage. Quest already got the game when they won their last clash with Aegis until Ammar just pick off during their high grounds just because he is greedy on getting Liquid supports in the backline instead of playing safe by destroying that T3 tower.
I think that he was tilted during that time, it's known that he's easy to get flamed. All of his games, he has dominated his lane but it's not just all about winning the lane but winning the game.
On the other hand. Zai is doing a great job pressuring all lanes when they are still behind gold and when they lose team fights. This is the reason why Quest can’t do high grounds immediately since they need to react on Zai pressure on all of their lanes.
And his item choice also helped, his lycan built scythe of vyse that did helped in locking down Quest's heroes.
Meanwhile Betboom made it to TI somehow
Not yet sure with that, waiting for Valve's decision if there's a penalty and minus points for BetBoom.
