I think something is bugged or they nerfed it .  

 i just spent 500 energy for 2 superior potions.  The events used to offer the arcane potions so farming was not required as much but they have been gone for awhile.   

Topic mentioned many times before. I agree with you in 100%.

Now let's answer you from typical 'plarium' point of view:

Player J said:

Can we remove something from level 15 Potion keeps?

'No. Give monies.'

Don’t you agree that a person who is able to Farm the highest possible level should get drops rewards which match there present situation?

'No. Gibbe monies.'

I currently am Farming lvl 15 Arcane Keep, I’m clearly looking for a Super Potion, Medium Potions, or Ancient Shards.

I shouldn’t have to get rewards similar to what beginning players Farming stage 5 are getting lol.

I don’t want XP Brews.

I would prefer Rank Up Chickens.

'and we prefer to fok your drops up to frustrate you and bored you to death so maybe you will buy them for real monies.'

Medium Potions, Super Potions, Ancient Shards, & Rank Up Chickens

Don’t you think this could be a more fitting drop reward for a player who is farming higher stages?

'No. Give us more monies.'

Lesser Potions, Meduim Potions, Mystery Shards, & XP Brews

Don’t you think this could be a more fitting drop reward for a player who is farming lower stages?

'No. Did we already mention that you can give us your monies?'

I think the game needs to relook at the Potion Dungeons.

I think something needs to be changed.

'We dont care but you can give us more monies.'

..and my personal favorite

This can’t be working as intended.

'But it is. Now stfu and give us monies.'

Hopefully I helped you more (or probably same) as typical plarium responds.

The next mission I had is to Farm 5 Super Magic Potions!

O M G

This is so ridiculous.

I farmed for 5 Super Magic Potion on Stage 15.

It took me all day.

I finally completed the mission 5 mins before the game reset!
