I'm about to start a Rogue Trader game and i'll be trying out the Nemesis path and asociated mechanics for the first time. I was wondering what sort of power level of base NPC profile have you found works well? Considering the NPC profiles run the gamut from lowly hive scum up to powerful throne agents, psykers and mercenaries, not to mention xenos. Looking at how over the top adding Build Points to an Eldar aspect warrior for example, and i'm not wanting to overwhelm the players at every turn by their nemesis. Thoughts?

if you build them to strong in the begining it would be easy to scale back i have not used any of the nemesis but as I said if hes to powerful its not hard to scale him back mid wrecking your PCs

I was underwhelmed with the Nemesis rules, disappointed even.

I'm not saying they are necessarily bad, but they didn't work very well for me.

I can only hope they work better for you.
