I would hardly say that that's the reason because she is more of a shaco except her mana pool is like 320 level 1 she has to use her hate spikes quite alot she can run out mana after a few waves if she isn't hitting all the minnions with her Q speaking of which your gonna need to poke down alot in lane to even do anything she is amazing in ganking like a shaco if they can get alot of ap yea they will both be pretty strong, but like a shaco she can fall off pretty easily without those kills as a jungler using 1/8 of your mana to engage a fight and trying to use it against to chase for a reset only to have it use up the last your mana can feel pretty bad for some people I'd think like when a poppy uses her ult and realizes she didn't have mana. She is an amazing jungler and laner depending on how well knowledged the player is, but if it should change the mana should scale up to 40 with runeglaive it may not be so bad,but until she gets it or some mana that passive won't help her regen mana at all
