6 weeks with no heavy synth sold in Xur... sorry but this isnt normal... for people who play raid every day or help friends to complete it this is a problem.. not everyone have 24h at day to farm glimmer and this make you say to your friends: sorry ive no heavy synth to help you... in addition.. you dont have sufficient glimmer to max you new weapons or max your armors/weapons that Xur restarts. And the "best" thing its that bug in heavy ammo its not fixed after 6 months of game... a bug that the first day exists and many people has been posting in the forums... so please.. you know this bug for mmmmm the last 3 weeks? Maybe Xur could trade the heavy synth until you fix it... but... now its too late for this... you will fix it in some days... in my little opinion... this game costs to you a millions of $ and I think that must dont have this bugs...
