In response to using portals to stack players and pop them into the middle of an army causing increased server load where models don’t load fast enough:

Hey all we have some plans to fix some of this. It is currently being looked at so expect a fix in the next few weeks. Basically we like that Portal has this power, but it shouldn’t be able to bypass walls, etc.
As for the problems with players not appearing this is a more difficult engine problem to solve. While we would like to solve it there are definitely counters to this strategy, because anyone doing it has just clumped up their entire team for AoE nuking. Ultimately if they outnumber you by a lot there are much more effective ways for them to kill you.
More interesting, does this mean we’ll see a nerf to the Portal skill where Mesmers won’t be able to hide out in keeps and open portals to allow people to sneak in?
