Wow congrats. It will probably be the best grass DPS, either quick move + Leaf Blade looks to be pretty damn good (idk the math on fury cutter's energy generation but it is really high and might make up for the lack of grass quick move damage). I'm sure there will be a use for grass damage in the future, so personally I would power it up (but then again, I like to max out any 100% that is good at something).

Sceptile use
I know he ain't gonna set pulses racing but treecko and sceptile were my fav hoenn starters and one of my all times. Got a level 32 (wow thanks weather) 100% treecko so all i need are 125 candies for a really good grass attacker but like should i expect much? Or am i better off grinding torchics or slakoths. Good thing is he is level 32 so no dust need be wasted. Could be good for groudon w solar beam maybe...
