Considering one of the only down points of trapping is that the traps have extremely long recharge times in comparison to all thier other abilities, Oathshot brings an intreting tactic to the table.
When you consider that a ranger with 16 expertise has a 21sec duration on Whirling Defence and around a 16sec blind using Throw dirt, an Oathshot trapper can effectiely disable a large segment of an IWAY team or any Ranger Spike team.

Res Sig
The premise of this build revolves around using oathshot to recharge Whirling Defence and Throw Dirt, considering that OathShot has a 20sec recharge this allows for the ranger to maintain whirling defence at all times. Throw Dirt pretty much disables all physical damage from Warriors and Rangers and the traps themselves just do AoE damage in other sectors of the battlefield.
The biggest downside to this build is the fact that the damage output is significantly decreased, however the damage denial from blinding 2-6 warriors for 16 seconds every 20 more than makes up for your sacrifice in damage.
However, this build is terrible for Team Arenas.
