Reduce passive uptime to 2 seconds (so you are forced to use charges immediately). Passive-empowered attacks reduce CD of BASIC abilties by 1 second. Damage increased from 20-50% to 30-60% (The idea is to move the damage from Q to innate, it would also teach new Riven players that they need to use that passive in a more "visual" way)

Q CD increased from 13 to 16 seconds. This compensates for the passive change. No longer has base damage (only the AD ratio). It would reduce free mobility and damage but reward for proper passive usage.

W CD increased from 11-7 to 12-8 seconds. Damage rescaled from 50-170 (+100% bonus AD) to 80-240 (+80% bonus AD). It would also make maxing W a more viable option (instead of having to level Q to even deal some damage).

E CD increased from 10-6 to 12-8 seconds. Shield rescaled from 90-210 (+100% bonus AD) to 80-240 (+80% bonus AD). AD scaling shield is OK but the scaling is a bit too high, some of it should be moved to base. Now resets AA timer on cast (feel more fluid).

R CD rescaled from 110/80/50 to 120/80/40. Duration reduced from 15 to 12 seconds.

Add mana (200 + 40 per level, that's 920 at level 18) and bring old HP5 back (I would do anything just to have that regen again). All abilities cost 40 mana per cast (that means Q costs a total of 120) and R costs 100/150/200. That's 300-400 for a full rotation, just on par with other champions.

Might be a bit too nerf-y (even though the passive buff is probably enough to compensate) but imo it would give a more solid/healthy basis for smaller adjustments. Moving more damage from Q to innate/W would promote Riven's intended gameplay and reduce her absurb snowball-iness (gotta admit, Riven becomes extremely faceroll-y when ahead, she can just REWQR and get a kill every time it is off cd).

Also, manaless is stupid by design (ironically a lot of my favorite champions -Riven, Kennen, Shyvana, Renek...- are manaless, and I wish they all had mana -even if that means moving their current resource into an additionnal passive- so their strengths could be moved in a more interesting part of their kit, and so people would whine less).
