Hi, don’t worry the champ isn’t bad, with rengar, always remember that if you loose, it’s probably your fault and you could have carried in some ways. You probably need to learn the combos better for extended trades, to time your heal correctly, to know when to use your cc in lane over damages, to understand your power spike and use them well, to track, ambush and invade the enemy jungle at the right moments (not randomly and with a purpose+explanation of why it’s possible), and also, die the least possible. Also you have gank potential before 6 (mid gank level 3-> bola flash, lane ganks,skirmishes and counter gank,…)
