For Hardcore servers, players should only be able to receive player buffs if you accept to be in a group together.
This should also include scrolls and other items that buff players on the same faction.
It should function the same as how you can not buff an orc player if you are gnome.
Being able to buff players while in open world can be used as a method to grief players on the same faction.
Example 1 - a mage blinks into 12 mobs and then buffs you with a rank 1 arcane intellect, putting your warrior in combat with those mobs. The mage ice blocks next to you and the 12 mobs blame you. Try again?
Example 2 - a rogue sprints into mobs and then throws a rank 1 scroll of protection at you, putting you in combat. Then vanishes next to you. Your warlock is now full of diseases. Rogues really do pick everything up from the floor, how ironic.
Example 3 - a paladin on a horse… just log out m8.
Buffs from other players being limited to groups should have always been apart of SSF. You are not truly naked if wearing other players buffs.
