The Varus nerfs only fixed half his problem. He still can't deal sustained DPS
Varus players have to rely on Q because Varus can't sustain damage with basic attacks. Varus can't kite at all. That's why nerfing his Q made his win rate drop over 6% from patch 7.4 to 7.5. It was so bad that even The Rift Herald pointed out in a column how badly that nerf gutted him. Once his Q got nerfed, he has nothing to fall back on. The other ADCs with no dashes or speed steroids (
and
) get vison spells, much larger AoE slows and basic attack steroids that can actually be cast. They both even have longer attack range - Ashe has it all the time and Kog has it 50% of the time before buying any CDR.
Nerfing Varus' Q was like putting a band-aid across a gaping chest wound. Sure, one could argue that it technically helped but I think we can all agree that the job was left undone
