Spirit also presently increases health regeneration outside of combat (with minor in combat regen for trolls)... really not worth it at this low a level for 19s with two exceptions... Rogues can get away with building a few pieces of a spirit regen to help with health regen in the off chance they do get out of combat to heal up some while remaining a moving target from an actively searching foe when eat/stealth is a risky proposition and bandages being either on cooldown or impractical. The second exception is a spirit weapon typically for the purpose of equiping while eating/drinking to minimize downtime. You don't typically don't want to go with more than just your weapons on the account that if you do get pulled into combat by a random lock dot or hunter shot or a rogue looking for an easy kill, you'll find yourself at a disadvantage in DPS, Burst Potential, and survivability.
