I've added Firefly on the Level 1 skill slot because you CAN and WILL die mid vs a good team. Even in pubs. Batrider isn't really THAT dangerous untill he is Level 2-3 anyway. So let the escape skill be 1st.
Tip: Try pulling enemy heroes through trees with your ultimate+firefly as deep as you can. Even after the ultimate is over they will have a hard time getting out of there while walking through your firefly.
