And thats not even the most important thing, the cd reduction will make it possible to be used twice in most encounters as long as those bossfights arent super short.
4pc looks kinda mediocore compared to the 2pc, just like any other setbonus, but i will let others calculate how big of an influence this is going to make. It may also change the behaviour of pre soulburning to get another shard in fights without an ability to get shards back from dying adds.

TL : DR 2pc looks very (too) strong and 4pc looks reasonably
