i said this many times before, but i honestly think the rates themselfs are fine as they are and that they don't need to be changed
but my problem and biggest concern is that we don't have that many oppurtunities to get shards, so i rly hope they will introduce new content where we will be able to get more shards and increase the drop rate for shards from dungeons, arena/clan boss/clan chests and increase the amount we get from market
they could even put something like void/sacred shard pieces to shop and chests
If drop rates are lower a lot of F2P will never get a legendary. if the only sacred shards they get are from Month end they will get on Avg 11 per year when on average it takes 17 sacred shards to get a legendary and that's being generous.
