gate-monkying and Vanguard charr quests

In Pre-Searing;

If u have a Vanguard Charr quest active and u Gate-Monkey for someone who doesnt (but is lvl10 or higher), and zone in together do the extra charr spawn, and remain when u leave ?!

If so, a nice way to provide extra charr to hunt for the other person !

GM etiquette is to leave prior to entry into the northlands.

Firstly im sure the other person would be farming the same quest so its a wasted effort.And as Andemius said - gm leaves before the payee enters the portal - eg gm runs to lever and customer is rdy to go thru first door when it opens , gm flicks lever and maps to town and customer runs into portal ensueing hes the only entry

should also be noted if the gate monkey stays and both zone, the levels of the charr spawns are decided by the lowest level person. for example if you are level 17 and the gate monkey is say level 10 then yes the charr will spawn but you won't get any experience for killing because you are more than 5 levels higher than them only the 1k xp for completion when you turn it in
