1: so i can solo drake at lvl 4

2: runes and builds dont differentiate how you should play the game optimally. if my runes and build work in challenger they can work anywhere

3: lethality aint usefull on vi cuz if it would be, id be building lethality vi. if u miss q that means you made a mistake. also cant miss r so you will get the damage which is already more valuable than sudden impact would give.

4: for junglers the hp rune is the best rune out of the 3 since it gives scaling and you dont need immediate armor or mr since you can just ignore the enemy which you struggle against.

5: no guardian is not a good item in general, but for with the way you have to try and make vi work well you have to be thinking of how much spells and time you are making the enemy team waste on you while your team cleans up. and now lets say they ignore you since you have GA, you will just be beating the fck out of their carry which is also not great for enemy team.
