hearthstone Hearthstone Community Contribution: Comparing to Pros Experiment

1 post in this topic

A Hearthstone player called Kjellstroem has uploaded a video of an experiment he conducted. He used 30-minute VODs from 5 professional players and he made a comparison of his decision on a specific turn versus the professional players' decision. His conclusions are quite interesting.

 

Kjellstroem uploaded his video on Reddit, where he received a lot of upvotes and positive responses. A quick explanation of the experiment: Kjellstroem chose five 30-minute VODs of five professionals playing five different decks (Thijs with a Druid, Lifecoach with a Rogue, Kolento with a Zoolock, SuperJJ with a Freeze Mage and Brian Kibler with a Patron Warrior).

 

Before each "real" decision Kjellstroem paused the game and made sure to decide exactly how he would play it before he resumed the game. A "real" decision is anything like the mulligan, playing a 2-drop in turn 2 instead of hero powering or adjusting a play after an RNG event, like a Knife Juggler juggle. Kjellstroem considered as "agree" any turn where he had made the exact same decision as the respective professional player and as "disagree" any turn where the decision was different, even if it meant playing the same card but doing a different trade.

 

Kjellstroem didn't focus so much on his own choices versus the choices of the 5 top players, but he emphasised on the conclusions of his experiment. He found out that the professional disagreed with his decisions 40% of the time, quite a big percentage. Around 40 times the profesionnals' play was correct/better than his, 20 times it was very close, while only 6-7 times the professionals actually made a mistaken play. This led Kjellstroem to conclude that being a good player is mostly a matter of skill, not RNG.

 

Obviously, some decks have more possible decisions than others. A Freeze Mage is much more straightforward than a Zoolock in late game. Last but not least, it is now scientifically proven that Lifecoach plays slower than other Hearthstone professionals!

 

 

Kjellstroem talks a bit slowly, but he explains everything quite clearly. You can also follow the relevant Reddit thread here. Finally, you can do the experiment for yourself, if you have the time, and share your results in the comments below!

      Im making a telegram bot that can send you new decks and news from https://www.icy-veins.com/hearthstone.
      It already can send some decks and filter them by class and deck format.
      Im going to open bot for all users in next few weeks. 
      Any suggestions?

      Blizzard have announced that the next Hearthstone year will be called The Year of the Mammoth. Six cards from the Classic set will be moved to a new Hall of Fame set, which can only be played in Wild.
      The announcement explains that the new Hall of Fame set will include cards that are currently in the Reward set, but the big news here is the six cards that will be leaving Standard. You can see Blizzard's reasons on the link above, but I've given a few notes in this article. Those cards are shown below.
      As well as the removed cards, there will be no adventures in 2017. Instead we will be given three full expansions that will be accompanied by a single-player mission, which will be used to enhance flavour, and offer challenges. This sounds like it will be along the lines of an adventure, but optional. I feel this is a great change, as it hurts nobody.

      Azure Drake is simply in too many decks. It is a hard card to nerf without making it weak, but it is pretty much as powerful as a 5-drop can be. Removing this to free up other 5-drops makes sense.

      The reasoning for Sylvanas is similar. Blizzard's words make a lot of sense on this one, and also give an insight into the future:
      Blizzard
      Similar to Azure Drake, it’s hard to see a card at the six mana cost out-value Sylvanas. In addition, Sylvanas has the most powerful Deathrattle effect in the game—as a comparison, the Priest card Mind Control costs 10 mana. We have exciting Deathrattle build-arounds coming soon, and in combination with Sylvanas, they would be too powerful for Standard. This seems to imply that N'Zoth, the Corruptor will be making a big comeback soon!

      I suspect a lot of people will be glad to see the back of Ragnaros. The Random element was often a contentious issue.

      The removal of Power Overwhelming is a bit of a surprise, but it seems that it has mainly been nerfed because of its strength in combinaton with cards like Leeroy Jenkins and Faceless Manipulator. I would also assume that Warlock is going to be getting some fun new toys to replace it.

      Ice Lance has been removed to remove Freeze Mage and allow new strategies to develop. It is also interesting that Blizzard mention it will allow them to make cards that copy cards. That could also apply to Power Overwhelming, so I would expect something along those lines to be in the next set.

      Conceal leaving will make sense to everyone. It allows Gadgetzan Auctioneer to survive as an interesting card, and removes the annoyance of not being able to interact with your opponent.
