I know they work independent of regular packs (e.g. you cannot expect the pity timer of reg packs to affect them at all) but does anyone know if they have their own counters? I ask because I've opened a few and have never gotten anything other than one rare. Itd be so hot to know that one day golden packs would pay off big.
I got golden Grommash Hellscream in the first one a epic in other two I have opened so I got pretty lucky. But you are right, pity timer is independent so it is just about luck since it seems you will never even get close to pity timer.
I used to be part of the 4/1 golden pack club. However, after the last adventure pre-order I got lucky and got a golden Illidan (not so lucky lol), a rare, and an epic. I think I've opened 3 total gold classic packs in my lifetime.
I do not believe they have a pity timer but I do believe that something is different about their drop rates for I have opened about three and gotten a legendary from two of them one being Hogger and the other Edwin. Also seem to more commonly drop epic cards too but it may just be lots of luck.
Edit: I am most likely wrong about the differing drop rates, it is just a theory.
They surely have their own pity timer, as for drop rates I'm pretty sure it's the same formula as a regular pack. I've opened 5 of them and viewed countless others on streams. It's usually 4 commons and a rare just as you'd expect from any normal pack. As normal Epics and Legendary can happen but it appears to be rarely.
On a side note I wish they would give these packs out more often and consider making some golden packs for current expansions instead of just classic. It's such a cool swag but they seldom ever have events or promotions that give them out. Most people who've even been playing HS since it's release 3 years ago have not gotten more than 3 gold packs. That's mighty stingy...
