A couple non-obvious notes if you try drafting:
In each round of packs (there are five rounds where each round starts with 12 cards and you take two at a time), you can take up to one hero. so once you take one you can’t take another until you get to the next round. If you don’t take enough heroes or items, you can fill your deck with basic-set ones, so you can take cards of whatever color without worrying that you don’t have enough heroes of that color.
You don’t get that for regular cards so if you don’t get enough creeps it’s not great.
The first pack you get has 12 cards in it. after you take two, you get a new pack with 10 cards in it, and the two missing cards are (i think) chosen to be two of the better cards in the pack, so the deeper you go the less useful the cards are. It’s not clear if it tries to emulate the people next to you being in colors (so you could try to be in different colors and thus get better cards), or even if they do the neat shadow draft thing that Eternal does, where it figures out what was taken by basically replaying drafts so the cards that got picked are cards that were picked in previous drafts.
It’s not clear to me that it’s trying to emulate real people vs just trying to make sure the card quality is decreasing, which you could do by just tracking how early each card normally gets chosen and then removing two of the higher-ranked cards each pass.
