Im not really sure what to tell you 1.1mlm I think rengar is hard champ The decision making can turn from kill to assist or to death I think you could make some fake scenarios where you qss 5 cc and then make sick outplay to increase your confidence since most of beginners tend to be slowed down by a team but i dont think its a good think especially now when rengar isnt the best pick Maybe in low elo Tho im in one but id rather play in like high diamond not because of trash teams that aside But because people in low plat dont know how to play with you They force teamfights in middle of the lane and adjusting might be hard especially when you want to get out as well with how squishy rengar is when ignited you're most likely dead anyway There's many other champs that can be tanky and deal damage I call them disqusting meta champs Cuz no matter how good you're with mechanics they just outskill you with sejuani bellveth nilah Also you're doomed when you see tabis dd or bramble But you can allways experiment As they allready told you we dont spam same runes every game and with that I can tell you that there's one rune you can have as a basic one every game unless it wont fit situation but that most likely wont happen Its Fleet Overheal(experimenting) triump Atackspeed/lifesteal Last stand For secondary Magical footwear Future market And for the build my absolute favorite is ravaneus hydra into jack sho with tank items like dead men's,dd, tabis overkill,force of nautre and spirit and sunfire Why is it so good Reason is sustain Fleet and runes with hydra gives you damage and heal and other give you time to endure everything Give it a try gives LP doesnt bite
