Those people chase after awards basically. Anything to get the fastest gains per possible this is one reason.
Another is aggro exsits to shutdown OTK pretty much. You ever see those decks in magic that funnel through just looking for what they need ignoring you to win? Aggro is supposed to checkmate that game design.
Heres the truth why people like you an myself dont like aggro. Because youre wanting to explore unique strats an combos of cards. But lets be honest its not very good. BUT we know HS has 10 mana as its limit so we wanna explore game play that involes max mana etc.
To the people who say aggro takes “skill” sit the f down, not in HS it doesnt. Decks are only 30 cards. Getting a perfect opener is beyond easy. The game is so tempo driven whoever goes first destroys people. You cant even interact with the opponent during there turn. Which is huge if youre used to playing magic for years. Thats why combo also sucks cause just a simple Counterspell would crush such an archetype.
Yes OP its boring just watching people drop cheap minions an hoping to get any form of burst to win like skill command, or snowball minions. People act like aggro is fine because BOARDWIPES. Boardwipes are trash when refills are way to easy to perform. To really control aggro we need stuff like Frostbolt aka Lightning bolt in magic to negate tough 1 drops.
If we had better control tools we could actually print legeit awesome aggro cards like 1 mana 4/3 it enters the battlefield unless you choose to take 4 damage. Then it doesnt enter the battlefield. But 30 card decks an apparently unlike magic where you can run mana rocks (aka ramp) in HS youre stuck with the stupid system of 1 mana per turn, then 2 crystals, then 3 etc. Which awards AGGRO waaaaaay more insanely than control who wants more mana asap to play its higher cost cards.
Tl;dr game caters to the easier archetype aggro than any other.
