5 min cooldown timer on all potions?!!!? Seriously!!!??? They only last 15 seconds or heal you for not even a 3rd of your hp, same with magic potions. This needs to be fixed too!
No. it's a minute or so on Potions and Hi-Potions and only spikes up to 5 minutes for the X-Ethers and stat boosts, 6 minutes for Elixrs, and 7 minutes for Hi-Elixers. I would rather the cooldowns on the latter two be dropped down to 5 minutes on them, but if I'm having to pop an X-Ether more than once every 5 minutes, then something is probably wrong with our party composition.

Agreed on the PVP though. We joke that SE earned the "You Tried" star on the MMO kindergarten board.
