Shards are hit and miss for me, but I think a great QoL change would be replacing the 90 day 5* reward with 500 shards for said character. Devs want to insert shards all over the place, this would be a very player friendly place imo
More than that, I’d love the HFH offer to be shards instead since we actually pay for that rather than it being a log in freebie. Waiting possibly years for the right color to come along can be a pain.
They can do it with DDQ as well.
I would like them to offer newer 4 star character covers over time for Days 2000+.
Careful what you ask for, they could go with an idea with that, but since 500 shards are worth more than 1 specific colored color, they might decide to give you 250 shards not the 500 you want.. making them be just one more collection of shards that sit unused.
