Hunter Potion underwhelming?

Just curious if anyone else was having problems jungling after the new patch update. I only tried it once and did it as .

Now, has never been the best jungle clearer in the world, at least early. Last patch I was able to do usually 3 jungle camps before having to go back to base. Now last night, I started Gromp had a good leash went to do blue and holy shit! killed him with like 40 hp to spare..... so had to back and bought the new hunters potion because it was the only thing i could afford and these 2 refillable potions weren't helping. Although I like the hunters potion idea, the 60 hp regen and minimal mana regen per charged seemed very underwhelming. I know the charges have to be fairly weak since you refill 1 after clearing a camp. But my experience was it was very underwhelming at first and I was doing all I could to survive to level 6. And then eventually the jungle was super easy mid to late game.

Yes, I was running runes and new masteries. Maybe I setup my masteries wrong but it almost feels like you will fall way behind unless you are playing certain jungles: i.e. (like in prior patches/seasons) . Just curious if anyone else felt the potions need to be buffed a bit or if I just need to switch up something.
