The best Druid spec in World of Warcraft Classic depends on a variety of factors such as the player's playstyle, the role they want to fill in a group, and the content they are tackling. However, there are a few popular Druid specs that are considered strong in different situations.
For PvP (Player vs. Player) combat, a balance Druid with a focus on interrupts and crowd control is a popular choice. They can use spells like Entangling Roots, Moonfire, and Hibernate to disrupt enemy players and control the battlefield.
For PvE (Player vs. Environment) content, the most popular Druid specs are Feral Combat (cat form) for melee damage and Restoration for healing.
Feral Combat Druids are known for their high burst damage and mobility, making them a popular choice for dungeons and raids. They are also very strong in solo play, as they can take on multiple enemies at once and survive with their stealth and self-healing abilities.
Restoration Druids are valued for their ability to provide strong and consistent healing to their group, making them an essential part of any raiding team. They have a variety of tools for keeping their allies alive, including direct healing spells, HoTs (Heal over Time), and powerful resurrections.
Ultimately, the best Druid spec for you will depend on your playstyle, group composition, and the content you are facing.
