Zero heirloom shards in 80 apex packs...

I have spent zero dollars on extra packs, only so far has bought one Battle Pass and that's for this season.

Have one set of Heirlooms, for Bloodhound.

While yes, I would like more, there's no way at the rate things are I would ever buy a pack just to get heirlooms.  If you don't want gray items from any one Apex pack, which is the only thing at all you can reliably count on getting, I wouldn't buy them.

Everything else is gambling and you should know that when you spend money on them.  Nobody goes to a casino getting mad because rng didn't have them come out winning.  It's the same for any loot box thing you buy in any video game.  You're gambling, that's what you're doing.
