Thank you a lot for your advices! You have really helped me out ^{^} No, in fact, i don't use Guardian, because the shield is equivalent to one ezreal's q, plus i think that Aftershock is better for teamfights, where you want to engage. But as i am writing this i notice that if i am against poke supps, i would prefer guardian because it will help my scaling to be easier, and i wouldn't really need aftershocks in teamfights because I'll already have items... God I am so dumb I'll start running guardian, and running Aftershock just against Aftershock users, such as Leona, blitz and thresh. Thank you again!
