With the nerfs to natural duration on jungle buffs coming in 6.9, can we make Runic Affinity better?

Runic Affinity is going to lose even more popularity with how jungle buffs are getting their durations reduced (except on first takes) to 90 seconds from 120 seconds. That 15% increase gets reduced from 18 seconds to 13.5 seconds, making it really unattractive.

Could we have Runic Affinity's percentage increased to compensate? At its present 15% value, it won't be a meaningful bonus; it'd just be a micro-optimization.
