this is a hindrance , I wanted to make a reskinned devidian in red whispers, but it would have bumped the level to 16.
I really wish we could make custom enemies and have a value table for each ability to prevent exploits, like in neverwinter night's aurora engine.
basically each ability contributes to an enemies level, so you can mix and match weapons, armor and powers to create a low level mob that might have one really great attack but is weak everywhere else, so you can create unique enemies.
I realize the devs are worried about exploits, and thats a valid concern, but if one of them could spend a day in that toolset and see what types of things they did to get around that it might be neat. The aurora toolset has had a long cycle to work on trail and error.
