I'm not really fond of the idea of the inn wiping buffs since there's a few buffs I can think of that would be inconvenient to wipe. (Food buffs, Hikari's Blessing, Prayer buffs, etc.)

That said, the effects can be visually annoying when you're outside of battle. And of course, you don't want people to start off PvP fights with Excel Charges, Astral Belt or Ice Point Guard.

I believe there was a suggestion for an option or at least one of the PvP modes (spar or serious) to get rid of pre-battle buffs like the above three examples. If we had that, I think there'd be no problem if Astral Belt and Ice Point Guard were only visible during battles.

I'm not sure having a PvP option by itself would be a fix. People might not consider to select the option out of habit or because they don't see any buffs on the opponent.

I could see the inn stripping buffs with exceptions (food wouldn't matter because that's applied at the start of battles), or perhaps being able to click effect boxes outside of battle to dismiss them (assuming they are positive, of course).
