Thanks for sharing the build.
I do think semi would be nice or hybrid because he has be very close to opponent for first skill.
And his role is also support mage.
It's such a waste not to get Fleeting Time though. You get FT and full 40% CD, you can cast the Ult multiple times in team fights even after you die because of CD from assists. This is super helpful endgame when taking down enemy turret. You and team can just keep respawning over and over while you kill enemy and take down the base.
Fleeting Time is definitely one the late game item. Buying it early game is a big mistake most players do nowadays. Faramis ult is not that usefull early game.
And most game I played, it rarely gets to late game. It is better to focus on defense/magic dmg rather then cooldown.
