Having trade/field craft to dish out the 28~60 shard reward more often than ventures isn't so bad of an idea (Giving a single venture from leves are kind bad idea tbh when people can just trade the easy 1k seal for 5). I don't think bots would spend their time on doings leve but most average player like me would. Reshuffling leves for the high shard reward are my kind of shard farming method for now until they decided to allow us to yield more shards in any way via gathering.
