Guys, I suspect if you want a clear gauge how difficult the contract will be, look carefully at the amount of reward offered. There is some indication that the reward indicates how tough a contract is going to be.
Yeah right now that’s basically the only indication (along with knowing the mission types since some, like town defense, are much harder than others)
But this isn’t really relevant to the issues being discussed in this thread though, which is “what *makes* missions harder” rather than “how hard are missions?”
