When hovering over an ability, the tooltip will tell you whether or not that attack is weak or strong against certain pet types. Additionally, you can hover over the opposing team's pets and view their attacks during combat. This will be important since it’s a good idea to pit a pet that's strong against the opponent's pet who's vulnerable to that type.
“To fill our pool of beta and stress test participants, we’ll be choosing dedicated players who meet select criteria from both the WoW Classic beta opt-in and the standard Warcraft beta opt-in. Participants will also need to have an active subscription or active game time on their Battle.net Account. While opting-in to the beta is the primary way to make sure you’re in the running to join the test it doesn’t guarantee an invitation to the closed beta test. We may also consider additional factors such as how long a player has been subscribed to the game so that we have the right mix of players to ensure great feedback toward making WoW Classic the very best experience for the community.”
Regardless of the brotherhood shared by the Illidari in their single-minded mission, there is a level of disconnect between Lord Illidan’s demon hunters and the rest of his forces. While this is by no means enforced, it is basically self-imposed by the demon hunters themselves, as the blood elves inhabiting the Grand Promenade had no issue to Vandel spending some of his free time there with their denizens. Furthermore, the bond of brotherhood is not as strong as one might expect between two demon hunters, as during their training and sparring sessions, there is nothing that stops one party from killing another so long as they maintain control of their inner-demons. Just the same, there are those within Illidan’s forces that zealously believe and follow his teachings, mentality, and machinations without question but it is not wholly uncommon for some demon hunters to either question, doubt, or even outright disagree with their lord’s ideals and methods.
You can opt in for the beta at the official site. When the beta launches on May 15, players who’ve gotten in will be able to play all the way from from level one to 30. WoW game director Ion Hazzikostas tells us that the beta will be “uncharacteristically small compared to our expansions,” in part to ensure that the focus is on the proper launch this August.
The system is automated, meaning that once slots are available, beta testers will be chosen, without any beta key to speak of. Kaivax then goes to stress the importance of your account security, stating that, “any third-party e-mail messages, websites, or in-game whispers that offer beta keys or access to the WoW Classic Beta should be considered illegitimate and ignored or reported.”
