My friend , i checked your history , and you are a big inter and feeder .
Work on your gameplay and learn game basics and you will 100% start win more
you have 28 % winrat after more than 100 games in iron , that totally not because of nasus being OP ...
but i let you know i'm a nasus otp ( plat ) and yeah nasus is free elo in iron , bronze , and silver and seems very OP , but that not the truth , once you reach high gold and plat ; if you are not a very good toplaner you will do nothing with nasus , and will be even better to switch into another champ.
nasus op in low elo because people are simply bad and they dont kite well , and they dont manage waves good a,d they dont stomp early what give nasus every condition he need to carry , same for yi , and many other champs.
i see lot of games where you leave the game after you die in lane or you get camped .
if you check my history you will finde a win with 0-10-0 , why ? cause a mega counter pick + 3 people camp and dives + internet , but did i left ? no i was mega behinde i had 1 choice to help my team = keep puching and force ennemies to come into me what gave my team time and dragons potentiel + farm time , at the end what happened ? my team was ahead a lot in term of lvl and farm and they carried me.
Be carriable my friend
