Good listing - have you got the same for Undead? Looks like an unpopular minion but thought it appropriate when making my toon - Rychor. He's only lvl 12 with 2 minions...
Check out the link that Nefarious posted, it's Zabrobo's (basically the king of masterminding) Power Listing.
you forgot that enforcers get maneuvers and then tactics with the first upgrade. pet only buffs.
Good info, im not sure if i wll roll a thug MM for a wile though.
BTW Aure, the link has closed 
Oh it dissappeared because of a reply of a reply of a reply of an innappropriate post, so half the thread is gone 
He posted that before the thread was, "cleaned up" shall we say 
At the time, the link was still working got me after he posted.
It's version 0.7 purely because I haven't got a Bruiser or the Tier 2 Upgrade yet, although I have had all Henchmen up to level 24.
