Any ideas how to get heirloom

lifeline heirloom tomorrow?  

After you get 2 free legendary weapon from the challenges, 7 *22 = $154

Basically your only free way is to keep creating new accounts, leveling those up to grind out the 45 or so free packs you can get untill you get the one you want.

Be sure to stock up on food and razors cause you'll probably shave your beard a couple of times before you get it.

Its a 0.2% drop chance btw.

Yeah getting the common crap out the way does help, but there's an insane amount of it when you factor in everything.
