Naoki Yoshida's Comment in Regard to Jump Potions/Boost Potions

[Nestama]

I love teaching new players. But there's a time and a place for it. End game content is not that place. If a blm in dzem needs help with rotation bring it on, no elitist attitude, love to help. But expert roulette fire3 spam? "I just started playing" cmon. It happens and it's annoying.

Then you either tell them to learn how to play (if it was indeed Expert Roulette), or kick them. Difference in playstyle can be a legitimate excuse to kick someone.

Im actually trying to prevent those "potions players" from harassment because that's what they gonna face if they have all the toolkit we have actually just after they use a potion.

Except they won't be harassed unless they say they used the potion and if they DO get harassed because they used the potion, then they can report the player for harassment.
If you really don't want a potion user (or rather, someone who has never done the fight ever at all like me who has never completed Thordan and Nidhogg EX but would like to) to join your farming party, then good news! PF is going to have a password system!
