I found a few posts to that topic scattered around somewhere and thought I open a new post for getting more into detail.
I can pick either a troll or a mino for my chaos dwarfs. Now, some people are against a mino because of current wild animal rules which may cause you too much turn overs.


I don't think this should be repeated here all over again.
But have you made experience with a troll on such a slow team? More reliable, yes...but what about really stupid?? Turnovers because of blocks? Too slow? Only good for early games? no real thread in your whole team for the backfield on defense??
