You guys are wrong, it takes 2-4seconds to teleport( +2seconds to equip it), using jetpack to run away with a streak is much better.
I agree that it is annoying to play events and someone randomly puts a portal in your way. I am going to suggest a yes/no windows asking if we want to warp or not. I think that this kind of windows should be used in every portal on the map (not events).
Anyone against it?
