Craftable btcoe rune arms

[Speed]

If craftable rune arm is bound to character on equip and bound to account shard is applied, then will it turn item into bound to account or still keep btcoe?
I also read that shards increase minimum level and it is advisable to put masterwork shard, but I guess it is all about old crafting system?

It keeps it's bound to character on equip status.

That is old crafting. the level of the item is static.
