He's really good at managing mana and csing without spells. When you look at when he comes back to lane at the 8:30 mark in the video he almost has full mana. No need to wait more time in base if you can just be on map and get guaranteed gold and exp from cs or kills/assists from roams/tp that you don't miss instead of theoretical gold from fountain regan. 2 seconds seems like a little, but everything counts like if he waited a little bit too long to tp at 11:50 then twitch could've gotten away and viego could have killed him.

@@Sangsal01 I understand that but even at 11:35 he is actually missing the mana he would have had if he came back to lane with full mana at 8:30. he was actually missing 120 mana at 8:30. If he had that mana he could have maybe pushed lane faster at 11:35. I guess its always a tradeoff but if you dont see an immediate need to run back to lane or tp somewhere quickly there is actually a lot of value in 100-200 mana, especially in early levels
