with this build you can just survive very long.
and can early make alone camps for support your team.

Strafe is good for run away and for atk the enemys bedder than Rain of vegeance because you hit the whole team and in the endgame the enemys run always together.

with Searing Attacks you can easily make towers and forts alone.

one thing ... the best build use nothing without a good team. so just lean to play together instad of run alone in the world ;)
