Well the traps/grenades are actually not bad especially if you go mech the main issue is that getting enough trap parts and other ingredients (soul gems are a giant PITA) to actually use them on a regular basis.
On the other hand with the dawn of U19 Mech actually got a bunch of cool abilities that are just cooldown based and their REALLY fun.
I also figured I'd work it as a Halfling Thrower build (if I'm gonna go gimp may as well go all the way :P)
Anyways I was originally making it a Single-Class Rogue but the Core 6 DWS ability is just WAY too awesome not to take (free 4 sec bluff every 6 sec) and honestly since it's Int-Based the DCs don't suffer too much.
