Are transmutation shards worth it?

Is it worth hoarding every blue item I come across and constantly profiling back to base to disenchant and get as many transmutation shards as possible? I’m level 24 now and still very much a new player. My inventory fills up fast because I constantly grab every single blue item and I portal home to disenchant. Is it worth doing that at this level? Or should I stop.

What shards / orbs should I be grinding for at this point?
