While true you can farm multiple characters at once. I am merely pointing out the rediculous amount of time it takes to farm in this game. Neither are unjustified nor pumped up and a fair amount of heros there is only a single hard node to farm. Limited characters have multiple nodes but I appreciate the input. At a single shard a day which is roughly a 5x20 for ls/ds hard node 20% drop rate it would take you 330 days. The math is hardly flawed for a single run through. Your assumptions are that rng will be favorable to reduce that time by getting more shards in 5 attempts. I however in my experience take a more pessimistic approach since the devs leave the drop rate so low anyway and like to limit the pace of the game. As a side note you feel that 200 days by your own calculations is equitable or reasonable time for a single character? This IMO takes away from the experience of the game and game play. Especially considering all of the various factions that are possible and needed to attain any goals in the game?
