One of the warrior buffs in 2.3 was a change to the pathing on intercept and intervene to make us less likely to have these abilities blocked by objects in the way (think of the pillars in the arenas).

A side-effect of this however has given us a bit of an exploit for warsong gulch (possibly blades edge arena as well - haven’t had a chance to try). Basically if a player is above you but technically “in range” for intervene, intercept, or charge you can now use the ability and you will be zoomed along to that point on the map.

In the video below, a healer waits on the roof, and when the warrior flag carrier gets into trouble he intervenes to the priest - sending him running at intercept speed down the tunnel, up the hill to the roof to get easily healed by the priest. Definitely a bug that will be fixed, but worth noting if you happen to find yourself in the gulch and see enemy warriors disappearing with the flag.
