"You're not only playing against the champion, you're playing against the player"
Just a general tip of advice.
My brother (currently climbing through silver.) constantly asks me at the start of games what he should buy first, level first, max first. How aggressive he should play in the early and when he should try to engage. I don't really mind helping him but at the same time I feel like he isn't retaining the information I give him so I decided to tell him "You're not only playing against the champion, you're playing against the player."
Yes some champions have advantages over others but there is a level of skill that trumps those advantages. Especially in gold and below.
I had been doing this myself for the longest time without realizing it. I spend a good 1-2 minutes of the lane analyzing how my opponent plays to know just what exactly it is I can do to beat them.
Which of course doesn't stop him from asking me how to itemize. In this situation I'll give you all the advice I gave to him. Press tab, look at who's fed, and build against them. Do you have the potential to insta gib them? Good, build to do that. Can't you survive their dps with the right items? Great, start building that. In higher elos when people have more focus you might want to start checking the death recap along with the score board to see who's focusing you and adapt to that.
or
to play very defensively until lvl 4, which is when he can get to the part where he stomps your face. 1-2 minutes of watching him play won't tell you how he plays, but knowing the matchup will.
,
(i know hes hated) and
. It wasnt until recently i started playing
and im finding that each champion is different in their approach to each match up. My biggest fustration is that i cant seem to remember all of them unless i play all day every day, which i have no time to do. But keep giving your brother as much support as you can. hell if i had a guide like that i dont think i would have any of the problems i do now
