I need help i don't know what items to build during a game (i always go the same build)
So just to get this out of the way... yes i am bronze trash but i want to get better and one thing i have never tried to fix is my builds i just use champion.gg and build almost 100% what it says to build even on champs i play often (its gotten to the point where i dont even switch up the order i never know when i should) so my question is how can i learn when i should build a certain item and when i shouldn't like for example i play vayne and i always go static shiv into ie which i know is really normal i mostly need help in the area between that and my last item on her which would be ga (most of the time, sometimes i say f it if i think i have to 1 v 5) i never know when to switch my items up be it the order or the whole build this mostly applies to ad champions i don't play tanks very often anymore but i know how to build them its simple (don't take that as hate i just learned it first) and ap champs are easy for me as well i play them often and have a good understanding but could still use help mostly i need help with ad champs i never know when i should go crit or life steal or even lethality (just a few examples) how can i get better at adapting? and please don't say "just play more" i know thats the best way to solve everything but i want to fix it sooner than later. anyone who took the time to read all of that... thanks!
if you're getting wrecked by CC every fight (remember to actually use the active)
early if they have a shit ton of armor stacking tanks
if they have a shit ton of sustain (mundo, swain, etc.), otherwise
