Quote:If someone declares hostility on you, you still should be able to use your party's portals.
Unless this already happens, in which case I probably sound like a complete fool... if someone hostiles you when you're in a party, that should be taken as a sign that they are hostiling the entire party, 8 players, 7 in a party, the other one hostiles, collective security. (Obviously this requires bigger parties, people being willing to support their friends etc.)
or better yet, that they are hostiling everyone in the game who isn't in THEIR party.
Some other solutions:
allow host to stop further players entering the game when they've got their 'ideal' party together
Have an 'opt in to hostiling' selection on game creation, rather than an opt out, since so many people don't play duel games it'd save far more mouse clicks.
Have people hostile to you show up on the mini-map right to the edge of the screen, as far as i can tell, they show up at a lesser distance that friends... that's crazy, you're going to be looking out for potential threats.
On the case of realism:
PK'ing doesn't fit into the story line; the seven evils are roaming the planet, demons are pouring in from hell, the entire world is being corrupted. A collection of heros is the last line of defense for the moral realm against this, they must succeed or the world will be consumed in fire... they start killing each other by suprise...
Notice the problem in this description?
