hey all my group after a long absences from playing 40k are picking up this edition and to cut to the chase, I'm going to be collecting Tyranids. firstly my regular opponents will be Orks, Blood Angels (with a strong death company element), Dark Angels (with a strong raven wing element) and Tau.
having not played 40k since Second Edition let alone with neds before, I'm looking for some does and don'ts

cheers!
