[@Necroes] I think the problem is not how powerful your character is, nor how fluff correct he is.

But as you stated with the ork weirdboys in your latest post, they are violent and only have a high setting.
That's why we're so annoyed when you claim your powers aren't visible until it's too late.
Weirdboys and psykers in general are known to be VERY obvious when they cast combat powers. Orks even more so.

So people would have a chance of dodging them, not saying it would be easy, not saying they won't take some damage even if they dodge.
I'm saying it's possible with most combat powers.
And psykers would have a moment or so more than others to react. Because of psyniscience.

And if you wanted to be neutral to the marines, why would you bring in the most destructive power you got and frikkin demolisher shell them?
Seems a bit contra-productive?

I for one support some gene-stealer cultists. Purestrain genestealers however are shitloads dangerous so if any of those appear i'd be hiding in a vent like a sissy :P
That way we could avoid tearing at each others throats, which is probably a good thing.
