This completely breaks my immersion

Yeah, I have a problem.

My Fast Skimmer with Aethersails moving 42" gets hit by a Guardman's rifle butt on a 3+.

Remember that talk we had a few days ago about good game design?  About immersion and how things make sense?  Yeah, the above absolutely kills all forms of imagination.

What about you folks?  What breaks your immersion in your gaming?

PS - I'm getting into BFG again.  My gaming group here's jumping in pretty hard.  Gonna play Craftworld Eldar, using the FAQ2010 rules.
