God bless the practice tool
i reached level 4 with riven almost by exclusively feeding ( new skin hype cant help it ) i didnt want to reach level 5 without taking something away from it
in almost an hour's worth of practice i've gotten myself a decent handle on the fast combo now. honestly it feels great.
side note: some how i managed to climb from bronze 1 0 lp to silver 5 in flex wilst only playng riven and yasuo top and losting lane 80% of the time.....
