A thread on the Blizzard Russian forum asks which class to choose in World of Warcraft: Forever for different modes; the discussion has three posts from three participants.

A thread titled "Which class do you think people should pick in World of Warcraft: Forever for fun?" appeared in the Russian section of the official Blizzard forum. The author asks which class fits PvP and PvE, and shares their own plan.

Their plan is a Warlock for PvP, a Warrior for PvE, on different characters for different modes: the Warlock to gank even high-level players, the Warrior "purely for chilling." The author themselves believes the only chance to have fun playing a Warrior in PvP is server launch, when opponents haven't reached level 60 yet; they name the Mage as an alternative to the Warlock.

Two people replied. In Lakrymosa's opinion, players will gank Warriors either way — so you should pick whatever you like. Lefis recommends a Warlock: more summoners in parties and raids is better for everyone.

In practice

Thin discussion: three posts isn't enough to judge class popularity in Forever. For picking a class, guides and dedicated discussions are more reliable than a single forum thread.
