A friend of mine was not too happy with this trait he feels the benefits do not out way the xp cost. I disagree I feel the ability to have a piece of Wargear that is always with you regardless of mission load out. AS I sead it could represent the Bolt Pistol that the first member of your family receive when he became a Space marine and ever member of you family is allowed to carry as mark of respect your ancestor accrued.
He felt that you should be able to take any 20 resource kit regardless of renown limits what do you all think
