I have been thinking about possible builds, and came up with the following as a potential starting point. The build assumes I will be using a Bow, and that the trigger delay on my trap will be off-set by slowing abilities.

I didn't get into the Beta, so I am not sure if juggling two different kinds of traps is difficult (e.g. targeting, placement etc.). This build is hopefully solid for both AoE and single target.

Any thoughts would be appreciated.
