This probably wasn't the exact reason worldwide summon got changed, but it sure must have been a start. One day I (as leader of Master) hear some complaints from a few people. Seems one of my fellow Masters, Rei, has joined up with this Entropy bozo named Ishmael (evil giant warrior).

They are summoning everyone in their pk range to a noexit room and bashing/fireballing them to death.

Imagine if worldwide summon worked nowadays? I know nightgaunts do a semblance of it, but there was no way to stop the summon. It worked to summon into guilds, etc.

Speaking of worldwide summon, a second memory is of one of Morgath's mortal chars, which was named Hammerbane.

Truck, Saher (I think), and I were leveling in Dragon Tower (the old one, not the current one) on the various ancient dragons, and Truck sees that Hammerbane is in pk range. He asks me to summon him and prepares to just deliver a massive beatdown. I say ok, and something that looks similar to this happens:

c summon hammerbane

Hammerbane arrives suddenly.
Hammerbane has left the game.
**edited to point out that back then there was no code for 'you don't feel safe enough to quit here'.

Truck mutters under his breath.
Truck says 'what a coward.'

You nod.
Saher chuckles politely.

Someone says 'yeah, what a wuss.'
(back then it didn't say "An Immortal")

Morgath slowly fades into existence.
Morgath says 'I'm going to smack him next time I see him.'

Uh huh.
