Restoration Shamans are arguably the most flexible support/healing spec in WoW Classic. Thanks to the fact that the Shaman class was developed as a hybrid (Tank, Caster DPS, and a Healer in one), they have access to buy classic wow gold a wide range of interesting Talents, abilities, and traits. For one, they can equip shields and cloth, leather, or mail armor, which makes them more flexible when gearing up. On top of that, they can use a Class-specific themed group of ground-based buffs called Totems.
With these, they can provide various damage-increasing buffs (Grace of Air Totem, Windfury Totem, and Strength of Earth Totem), help their group with top-level utility (Tremor Totem, Poison Cleansing Totem), or help with group’s sustain and longevity (Mana Tide Totem, Stoneskin Totem, Windwall Totem). If this wasn’t enough, they also have access to the only cost-effective “Group Healing” ability of Classic in the form of Chain Heal;
an ability that heals 3 friendly characters with every cast (if targeted at a group member, it will bounce between other group members only, which makes it somewhat predictable and provides reliable Raid-wide heals if Resto Shamans are spread evenly between Raid groups). All of this sounds already incredible and we didn’t even mention Shaman’s non-Totem utility abilities…
they have access to the best interrupt in the game in a form of the Earth Shock (it’s regarded as the best because it has the shortest cooldown of just 6 seconds), Purge that removes magic effects from the Target (this is great for both PvE and PvP as it can be used to dispell buffs and other powerful magic-based effects), and Frost Shock that can be used to permanently slow an enemy (Frost Shock’s slow effect is longer than its cooldown).
If there is one thing that slows Resto Shamans down, it is their low sustain. They can run out of mana very quickly if they don’t manage it properly (downranking spells, understanding how mana regeneration works, and stocking up on consumables is necessary when rolling a Resto Shaman).
Restoration Shamans are, by far, the most welcomed healers on the horde side and the fact that Totem buffs only affect the Shaman’s main group makes them even more popular in Raids (each group needs a Shaman because everyone wants those buffs and utility).
