I think the rules were not fully clear for someone who didn't play digital card games since Hearts (Dame de Pique).
I thought the game would be played like a physical game. It means:
- 90 cards out of 160 would be showed for picking,
- and we would play with our 30 chosen cards (no duplicates).
I guess the mechanics of the game come from Hearthstone (or similar) and I guess it works but I think I may have prefered if it was like physical cards. This is also to reply to this comment above « Currently you don't need a "strategy" thinking ». I agree with this comment. To me the reasons are:
- too much randomness (guessing the draft of the opponent or his cards in hand is too random - maybe it was biased in Legend league since most of players used the same draft algorithm (according to their feedback) which might have made it easier to guess the opponent cards); I don't know about Hearthstone but in a physical game, we would see the cards picked by the opponent which helps to build a strategy (even to decide what card to pick next).
- playing a card immediately without using its full efficiency is not so disadvantageous since it can be duplicated in the deck, so there are more chance to play it again; if a card would have only one chance to appear, you would need to think twice before playing it.
Anyway the current game version makes the job and what was valuable was to be able to perform by using different AI algorithms.
My two cents and my thoughts.
