Rivens hp regeneration
Riven has low hp/5. This is unfair because her weak earlygame, (before she gets the snowball she 100% needs but shouldnt get unless someone does a laughable mistake) is lame anyways. Riven has no innate sustain. Compared to champions like fiora, dr mundo and heimerdinger, riven has no lane phase. We can fix this, and make riven sligtly more viable by multiplying her base hp regeneration by 9.
has low hp/5 because she can mitigate a ton of damage with good usage of her shield. Long time ago, she used to have one of the best hp/5's, but she was also REALLY op then (I still remember the first time I ever saw a 4xBT+CDR boots+GA Riven back in those days...shudders; for context this was like late season 2 or even earlier).
... which used to have lifesteal and still does have bonus health regen on it, fixing her problem a little.
