I'm running this build with a lot of sub par pieces (str hexing pants and no gem in neck) and I can clear GR45 in 2-3 minutes every time. T 10 takes 2-4 minutes depending on Rift layout. The important thing is to keep moving so your pets reset and pull up to cleave what you're next to. If you're not resetting your pets correctly and are just letting them run around it's going to take a long time. I prefer to run aquilla's for the extra toughness to make it even more lazy, but other than that - provstgaard has excellent suggestions above!
