First, the Reflect Damage mobs. I am killing myself repeatedly. I've tried Smoke Screening the damage, but I run out of discipline very fast from having to use Caltrops for kiting as well. I've tried moderating my damage to taking them down very slowly, potting, and doing it again. That strategy is effective, however it takes decades to kill the mobs because I have to wait to deal damage for 30 seconds between health pots while kiting circles. That's what I'm dealing with.
Second, Fast mobs. I can't kite them. Same discipline problem, I use Caltrops to immobilize for kiting, but I run out of discipline and they just run straight up to me and smack me. I've tried a stampede build which helped wonders on the mobs. It definitely bought time for discipline regen for another one or two caltrops before running out and getting smacked again. However, not effective enough.
Please do not reply if you do not have experience dealing with Act II+ Inferno mobs of these types.
