This may or may not get flamed... let's see how it turns out.
Give characters that just move onto a map 10 seconds immunity. For those 10 seconds, players cannot attack, get spells cast onto them, nor can they cast spells on themselves. All they can do is move around on the map. If they try to cast a spell themselves or attack another player themselves then the 10 seconds immunity wears off and they can get hit.
Reason this is necessary: a lot of times players PK in WG market and end up portal camping. As soon as someone shows up on the map, they fw or multi/xice/xfire. Sometimes it's not the person who is PKing back but an innocent player going onto the map. This will give those players the chance to run out of harm's way or do an initial defense buff before they get hit by the spawn point campers. Also will make PvP more fair so that PvPers aren't instantly killed upon going onto the map and makes it a slightly more fair fight.
Suggestions? Criticisms? This is possibly not the best solution but not everyone knows the Lethe Mountains connects to WG... also althought you already get like a mini-version of this, I don't think spells like fw and xice are immune to that mini-immunity when you first get on a map. You just can't target/click on a person.
