Store packs were always meh, nothing was ever guaranteed unless you spent FP with worse probabilities. Drafts have a pity counter for both pools A and B, while the gem store packs never did. And the rest of the store? Looks the same, things you can get if you spend cash? The only negative thing with the change from store packs to drafts is that the game gives out a lot fewer tradeable cards, otherwise its an improvement.
If it's confusing, have a look at some of the guides here or places like the fifamobileguide portal.
