Rotbone's maps vary quite a bit in how they need to be tackled, but I think this team setup will generally do the job one way or another now that Re'vas can't take down Blightlord Terminators with ease. The general principles of separating Rotbone from the Terminators, using Eldryon and Rho to make short work of them ASAP and then luring Rotbone into open ground and surrounding him before he is able to hide in a corner are all good things to try and achieve whilst attacking him. Using Poxwalkers to start spawning mechanical summons right away is not possible on every map, but should be done whenever it is and your strategy crafted to accommodate this.
