Buff on hit ADC's that don't go crit.

The Crit Marksmen item changes have shown some pretty positive effects as Marksmen now scale earlier to be more relevant in this early game focused meta. However on-hit Marksmen such as seem to have been left in the dust and completely overshadowed compared to a crit version. Can we fix this? (This may be me being biased because i'm a main) but I dont think its right to try to fix the Marksmen role and not buff some on hit marksmen while their crit counterparts have gotten better by a substantial amount.
