I guess I cannot see why both of us cannot get what we want. There's no reason fragments cannot be added to daily logins, but not at the cost of the sacred shard removal.
After thinking about it some more, I came to realize why this change sits so uncomfortably with me. I see it as a change that removes some agency from players. When a person gets a sacred shard, they get a chance to interact with many other areas of game, including summon rush, champion chase, 2x summon events, 10x summon events, fusion/fragment events, guaranteed legendary (e.g. use 12 x sacreds, get a specific one on the last pull), etc. When they instead get some fragments, they don't really gain anything, except to wait for 4 months for that reward to materialize.
It's this loss of choice that bothers me the most. Plarium is asking me to play the game and by giving shards out I am doing that. But by removing shards, they are reducing the ability to participate in any number of the above functions.
There's nothing wrong with giving people free rewards and legendaries (we've seen this with Ninja), but I'd rather they didn't do it by reducing the options people have to engage in the game
