If the majority of people were afforded the opportunity to obtain these guns prior to HoW then it is completely fair. The only ones this may be unfair to are the people who picked up the game post HoW which isnt many. If you didnt grind for your opportunity at one, can only blame yourself. The claim that you didnt have enough time in the week to do it either will also invalidate your arguemnt as you cant expect to put in less work for the same rewards since its not RNG.
