I have the choice between that trinket and ring wich one first i got spirit of sun 496 and inscribed bag trinket for meagera.
Soothing is far superior to Inscriber bag (I have both). The bag has a low proc rate, and it's absorb shield is eaten almost instantly. As a pally we are able to do something similar (& better) cheaper and easier. The mana regen from soothing just stomps it.
