Okay, so here's the situation. Our Tinashi is talking about being able to use the teleport through the "final bush" (that specifically has health per hero, and must be defeated in a single round) to pick up the objective and win the map.
As OL, I'm calling B.S. on this ability - only on the recourse of totally breaking the objective of the map.
Is there a ruling somewhere that prevents Tinashi from teleporting through a barrier as such?
