Wow Healing Classes-Druid and Shaman

It's arguable that the healer is considered as one of the most important members of any raid team. Blizzard has given us a myriad of choices for healing classes. We here will review the pros and cons of Druid and Shaman as well the contributions they make in a raid group.
In Massive Multiple online games, there are a variety of aspects of healing that are the same from game to game. When analyzing any healing class in any MMO, it is very important to get to know these basic principles.
Long time ago, many people have been begging for Restoration Druids to be nerfed since they have a buffet of talents that make them appear more powerful than other classes. Most of their spells are instant casts, giving them mobility. They can throw out HoT spells on main tanks and other raid members while swiftly moving out of danger. This comes in handy during fights that require lots of movements like the "Dance, Dance Revolution" fight with Heigan in Naxxramus. They have more HoT spells than any other class and what's more, some of them stack, making the HPS even more effective. They also have a spell that is an AoE and a HoT all in one. Innervate is another useful tool that Druids have as it increases the target's spirit based mana regeneration by 400% and allows mana to fully regenerate while casting. Druids also have the invaluable ability to resurrect a team member during combat. Druids do well healing single targets like main and off tanks.
Druids are leather wearers so if the tanks aren't watching carefully, these healers can be taken down quickly by bosses and mobs. When a Druid dies, the group loses their battle rez and Innervate along with the flurry of HoT spells that can keep a tank alive during strenuous battles. In order to maintain the spell and the cool-down is very long, Druids must keep channeling, although they possess one Area of Effect spell in Tranquility. With the exception of that, this spell is a huge threat generator and means certain death for any restoration Druid that dares utilize this during combat. These healers are not ideal for multiple targets.
Priests were referred to as the one class that was created for the sole purpose of healing and reigned supreme over them all back in the early World of Warcraft days. They are armed with more healing spells than the other classes and have a palette that includes HoT spells, AoEs and a variety of direct healing spells. They also have the ability to control aggro and can buff other team members.
As a Holy Priest, the first healing class we ever played which we leveled to 70. We planed to start anew with a restoration Shaman and have not been able to play Priest ever since after being constantly killed within seconds of being targeted in PvP. There are two main reasons like rapid mana depletion and low survivability, which contribute to this lack of desire. Also, Priests only method of recouping mana is a spell that has to be channeled. When going OOM in the middle of a boss fight, this is very difficult to do.
