Mastery "Summoners Insight" accidental or intentional nerf? - 5.1

This is regarding junglers using the Summoners Insight mastery. It used to be useful as a jungle invasion tool for the early game (lvl 2-3 ish) with the purpose of having the advantage of a lower smite cooldown to contest camps, force advantageous stalls, as well as allow you to slightly modify the cooldown to match a specific jungle clearing speed, so that you could have smite up at specific points in time to get the buffs buffs you want in early game. The second reason was much more niche than the first.

Yes, it's quite rare that junglers are run with points in the utility tree (though, I tended to do it whenever I saw a specific type of invade opportunity), but the uses were very clear, with the obvious trade-off being that one must invest in the utility tree as a jungler.

With the new patch, the mastery does not reduce Smite's charge ammunition system, but just the 15 second cooldown down to 14 seconds.

Could this niche strategic diversity be restored by allowing Summoners Insight to slightly allow you to outpace the opponent's smite again?
