What do yall use? Particularly for HBM. What "goes together"?
I don't use any troops for HBM for a few reasons. First, sometimes they kill too many on the first wave, and the remaining enemies can't destroy my outer buildings fast enough, so it times out. Second, if you rely on troops to help you beat it, it can get expensive and time consuming to keep replacing them.
I only use troops for raiding, and lately I only use thopters. Lots of people use griffins for their firepower, but I prefer thopters for their HP and depend on my heroes for firepower.
I wish there was more strategy for troops. Maybe the mystery "troop talents" will fix that one day.
