I think that can be attributed to more cheesey top laners being meta like
who can just dick on melee champs. Though honestly idk why she's got such low damage. I'd say this tho, riven being able to just straight run people down in lane should almost never be a viable option unless it's against someone with shitty laning. The cost for damage should be a hit to mobility. If im an immobile champion, and you out damage AND outrun me, i now have to play the game in constant fear of just being murdered with no counterplay. Where as if I can out damage you but not outrun you. You just have to ward and be wary of me, but can play further extended and CS while still being safe. A champion who can determine when they interact with other champs is not healthy design IMO.
My best guess is, the issue doesn't lie within Riven's damage but more likely within her ability to survive. Since everything and anything deals damage, Riven really has to pick fights carefully because her shield simply isn't what it used to be. When Riven engages her shield is the only form of escape she has, and even that isn't enough to keep her healthy.
If you look back at the patch notes, Riot keeps increasing her health regen, which is a sign of what I previously mentioned. I'm pretty sure this is purely because Riot is afraid of backlash from the community if they did something like put damage reduction on her E, or re-vamped her passive to also heal a portion of her health. These are things that would help Riven, but also would make the the player base cry for Riven nerfs once more, since she's always been a champion that many players do not like.
