The Sentinel Cleric soul is a versatile healing soul that can be used for either 5-mans or raiding. It offers a wide range of single target, bursty heals with various cast times and a decent amount of AoE healing that can even do well in a raid with the right soul pairing. Sentinel also has a good number of cooldowns and tank cooldowns. In a 5-man Expert, it makes an excellent solo healing soul. In a raid, Sentinels can offer some of the versatility of a Chloromancer as well as a palette of useful cooldows for progression attempts.
There are a few solid Sentinel specs out there, but here are two– the 61 Sentinel / 12 Warden / 3 Inquisitor and the 61 Sentinel / 15 Purifier / 0 Warden. The spec with Warden is more suited for healing in a raid environment while the spec with Purifier is better for 5-man Experts and other smaller group content.
