Training an I/L to 50

I'm also training an I/L to 50 for the ring event. What I'm personally doing is using a self 30 minute 2x buff once a day at White Mama Monkeys at Golden Temple, and then heading over to Truckers and mobbing like hell with Lightning. Truckers are weak to lightning, plus the mobs are insane and you can snipe from on top of signs/steps. It's a great training spot and I think I'll be staying there until I hit 50.
Oh and, I started at Truckers at 35. You'll miss a bit and the pot burn is a bit high but it's well worth it.
