Read the following passages and answer the questions. A. Ranked mode was with the game since the beginning, though the first season was much different than what we have today. Later ranks took 10 or even 20 stars to complete, but in exchange, it was literally just the one season for about a year and a half until 2016 and gave us what we have today: 5 stars per rank, resets every 5 weeks. Back then, the problems with ranked mode were even more pronounced since with no resets practically everyone who had ever played the game for a significant amount of time was ultimate league, lowering the importance of the rank even more than it is right now. B. Currently, ranked mode is the most competitive mode in the game by nature of actually attempting to place players based on their skill level, and short of manually doing something like a tournament which takes effort or specifically finding someone to test decks with (which also takes effort) it's the only real way to test decks. The problem, of course, is that it's a very poor method of testing decks for a number of reasons. C. Because you're completely incapable of dropping ranks, a good win rate is not even particularly required to climb. This makes the rank you're at mostly meaningless since it's much more of a function of time played than it is actual skill or deckbuilding, and makes the quality of decks encountered quite poor due to there being no inherent system forcing you to improve. D. Because you're able to climb with poor decks, people do so. This creates a feedback loop where because you are able to climb with poor decks, the deck quality gets lower, which makes it easier to climb with poor decks and makes the deck quality even lower, and so on until we get to where we are today where decks that would fall apart to a stiff breeze see a win rate of 90% because they counter the most common deck on the ranked mode: the pile. Conversely, when tested in friendly matches or tournaments with much higher deck quality (and high sample sizes to compensate for inherent inconsistency in low sample sizes of games) in the aggressive departments, those decks fall apart quite easily since the pressure punishes their inconsistency and they're generally unable to get their gameplans off due to how slow they are. A/ Which sections contain the following information? Origin of the ranked mode The most combative way to find someone to battle in the game. A mention of another better way to test decks. An explanation why ranked doesn't need actual skills A period when the ranked mode was at the bottom of importance. A mention of an archetype dominating ranked mode. B/ Decide if the following statements are T/F/NG Being on the ultimate league in 2016 is insignificant in how skilled you are. Ranked mode is the best way to test decks. Your level of skill is always proportional to how far you reach in the ranked mode. Decks that lose to aggressive decks have the worst win rate in tournaments. Decks without a good win rate won't perform well in the ranked mode. The higher rank you are, the more time you invest in the ranked mode. C/ Complete the statements below with the given endings. A. ... is a reason why 2016 had a more noticeable problem than the present. B. ... creates a feedback loop where people keep playing bad decks. C. ... requires actual deckbuilding skill. D. ... loses to an aggressive setting. E. ... punishes inconsistency in many decks. F. ... becomes so-called good decks due to how successful they are in the ranked mode. G. ... is a remedy to the already existed inconsistency of the ranked mode H. ... only requires an invest in time. 1. Playing bad decks in the ranked mode... 2. Tournaments or friendly battles... 3. "Climbing ranks"... 4. Practically no reset in season...
