Hi, my name is speez and I'm a plat rengar main. I've played him Top and jg but mostly top and it was super easy to get to plat with him

PROS
Amazing early game
Good roaming
Great mobility
Good sustain in lane
***** on most champs top

CONS
Not the best into most meta picks right now
must roam to beat out tanks before they outscale you
lategame you have to play very smart or you just die to cc
VERY WEAK TO CC LIKE KNOCK UPS

You want to play as an assassin even if you don't have any assassin items and opted for bruiser items instead, play in the back lane till you see an opportunity to make a play on adcs or squishy mids or jgs

Late game is not your best friend, you mostly want to be looking for picks on is positioned enemies but at this point, if you are ahead they will always group as 5 so look out for is positioned enemies or split pushers.

Thank you for reading my guide if you got this far, an upvote would be nice I put a good amount of time into this because I noticed they are barely any rengar guides, any who good luck on your climbing adventures and I always will hope the best for you :)
