That is a total assumption...experience or not...
Even MMP doesn't accept all their own Q&A, when given the chance to incorporate Q&A in the ASLRBv2, many Q&A were left out. If there is ever an ASLRBv3 I feel confident in saying that not all Q&A will be incorporated...will the Q&A in question be incorporated? Probably not since it is related to a CG. Also, a Q&A can't be accepted cart blanch unless everyone has access to the Q&A...and we know that not every ASL player has access to all Q&A.
The same can't be said for your house rules unless I have previously played in your house.
Well, in the case of the Q&A in question, I never had to ask since everyone I have ever play CG with/against also assumed that equipment could be freely exchanged between units during a Refit Phase...so...wrong again.
On your 2nd point, the mechanics of play allow SW/Guns to be "dropped", then repossessed by another unit.
During play, sure...however, there is no step for such action during the ReFit phase.
An AFV can't "drop" an armor leader; abandonment is the only play method that can accomplish that.
Agreed...but then I am not talking about abandonment. I am talking about freely exchanging equipment between units during the ReFit phase. It is not expressly allowed. So if crews can't swap vehicles (equipment) then neither can any other units...unless you want to use an HR.
