The Ability Gluttony. Why is it so bad?

Gluttony!
Ability Description in PMU: When you eat a berry you will gain the berry"s effect & a little bit of HP. BUT here is the bit I am arguing for, it makes belly consumption twice as much as a Pokémon without Gluttony

Doesn"t that say something?

All these very underused Pokémon are being hindered by their ability, is this FAIR?
In my opinion it ISN"T!
So staff please listen to my vouch, please remove this awful hinderance on this pretty crummy to start with ability, these Pokémon don"t deserve hinderances, overpowered Pokémon like Archeops (With Defeatist) & Slaking (With Traunt) deserve hinderances, not poor Linoone.
So staff, if you want to do something to help please help by emoving the hinderance!
Thank You! For listening to my vouch!

Well, that’s PMD description. As far as competitive battling, the ability gluttony only has GOOD use in Little Cup, because of encouragement of using a held item. So basically at 50% HP rather than 25% HP. Being PMD/PMU you have to click ‘Eat/Use" there’s no use for gluttony.
The definition of gluttony: habitual eating to excess. Thus being belly is reduced more. (Meaning you need to feed the pokemon more.) I find it quite fair/unfair.
A.) It makes sense.
B.) It does make those pokemon HARDER to train. Pokemon with gluttony wouldn’t be useful in HT or any long dungeons for that matter.
Though I do agree part of it is unfair, but it was how it’s programmed. I don’t think staff would remove the ‘hindrance’ of these Pokemon’

Sense? ._. Since when does Pokémon make sense Rattata can make flaming wheels & Lapras can fire thunderbolts.
But thanks for you’r opinion :\ Hopes this doesn’t get ignored like last time

We don’t make the rules, I believe nintendo/game freak gave those pokemon that ability. We did not.
We wish to make PMU as close to the actual games as possible.
If you love the pokemon enough to use it, you have to accept it’s flaws.
