2 is good, usually. 2 ACC, 2-3 DAM, 1 or two of anything else you can enhance. Slows, KB, -Def, procs, etc.
That is correct, 2 SO's worth of accuracy is usually enough for most any situation.
IMO, I go 3-2-1. Tier 1 has 3 (Seeing as they end up being two levels below you). Tier 2 has 2, as they end up being one level below you), and Tier 3 has 1, since (Brainfart) they end up being your level (?).
But with Tactics, you could probably skate by with just two Accuracy in Tier 1 henchies.
Seven years of heroism. Seven years of friendships. Seven years of saving the world. Seven years of virtuous selflessness.
You will return, for you are the mighty City of Paragon, the City of Heroes.
For each Tier of Henchmen, assuming Tactics and Supremecy?
