It being hard means nothing, the lighthouse is exclusive to the people that don't lose on a card, as is the emblem. The year 1 emblem is exclusive to people that have participated in all aspects of content, from leveling up, participating in public events to completing the story aspects of Destiny, which Skolas is a big part of. Saying getting flawless should be a requirement is like saying getting flawless raider should be a requirement, both are acheivements sure, people have varying difficulties getting them yes, but at the end of the day, getting Flawless in trials is basically the flawless raider of crucible and has nothing to do with completing content or participating in the community that is destiny. This year 1 emblem is not meant to be super difficult to get, it is meant to showoff that you were engaged enough within Destiny and it's community to take part in and complete all of the content available in year 1, it is not a signifier of skill or anything else, it is a symbol of dedication to Destiny players.
