I also think it's best as sword and board (which gives you even more survivability as a ranged user)
A shield can give 18% crit hit chance to seismic slam
not on profile, but:
-5 weapon throw belt (cheap)
9-10% crit chance +7/8% seismic slam shield (also cheap, like a million)
here is a build i have used to great success in low mp as a sword and board with this build"
Remember to use overpower for the crit chance, not for the damage, so use overpower before you slap down a bunch of slams, you will reset overpower faster than 6 seconds, allowing you to constantly have extra 10% crit...
with some better gear you can make some changes, like ik complete set bonus instead of animosity, etc...
I use throwing hammer to use throwing weapon to control the battlefield, make choke points and stunlock kill any stragglers/elites/bosses, you don't even need to use slam vs azmodan for instance.
If you do things properly you can be running sprint marathon the whole time and nevers slow down...
you stay ranged the whole time. you don't need to use the worthless vs single target and low proc chance ricochet, it's been pretty powerful
