Invoker T13 Speedfarming Crusader Build
http://www.diablofans.com/builds/81372-invoker-t13-speedfarming
The build is pretty solid, effective and moderately speedy. I use it a lot in groups and solo, if i don’t want to switch to LON all the time. Yeah, and i like Invokers too! 
Trash is much more problem here than elites. It’s hard to kill trash with Steed Charge even when Reflective Skin is on. This is because LON multiplies everything by 13x, thorns uncluding. With Invoker however, your thorns is only increased through 2pc, when you attack or block. So most of your damage unleashes when you actually engage mobs in melee combat.
I prefer skipping small packs of trash and just go for elites.
