I think Hansels have a huge advantage, actually. They can perform all actions and can be extremely deadly against an attack build. Assassinations, I believe, are the second most valuable action in system wars, in terms of how they calculate into the final plunder calculation of the war. So a Hansel could assassinate their target down to a low troop level, then attack away till their opponent is pinned. This could earn them more plunder than any other build type.
