I agree with all the people who wanna make all ARs on your current level mandatory to unlock the roulette. There's duties in Trials roulette where I am grateful my friend didn't unlock them cause they suck (Hildibrand, Relic) but there's plenty of good mandatory duties to outbalance them. Frankly, I also think the Normal Raid series should be required up to your current level, because if I have to see A2 one more time, I might literally die.
