Just so we're all clear, you can take a two-handed weapon like the Relic Blade and a Storm Shield on the same model. I've recently just run through a rash of relative new players that seem to think that using a Relic Blade and a SS is not possible -- that is patently false. The only reason why they are classified as two-handed is so that you don't have players buying two of them and getting that +1 attack for two CCWs. Because, believe me, I'd be paying the posts to give my Chapter Master two S6 AP3 relic blades that hit at regular iniative!
Anyone else encountered problems or arguments over this issue?
