[Witchhunter]Explosive Shot/Grenade Grenadier, T15 Maps cleared

Hi, I’ve been looking for a build with Explosive Shot and Explosive Grenade as I find the combo clears much faster (im still in the early-mid game @ Lv 58) so thanks for providing some important info. At present how do you think the build holds?

even if you have fatter gear, you will always have defensive problems with the build, it is more like you kill bosses and they kill you, no loot, but map complete :)

Any thoughts on using Ryslatha's Coil as a Unique belt replacement? (DMG)
