Re: Ability drops in packs

I got all the plant alternates pretty quickly, have had them for ages.  I finished getting all the legendary characters a month or two ago.  Yet I am still short about a half dozen of the zombie alternate abilities.

When I'm not saving for something, all I buy is amazing brainz packs, yet last night was the first time in months that I've gotten an ability from one, the wooden dummy shield.  I don't know what's up with the drop rate for these, but it's been driving me bananas.
