Bringing exploration into a game is simple: promote it by rewarding players for exploring. Rewards can be a multitude of things, depending on what they discover. Obviously that may not be the design goals for World of Alkora since I'm not on the team, but it's one example.
Teamwork can be promoted in the ways mentioned above as well. Reward players for working together(I'm almost certain what KhaN means by teamwork is players working together to acheive a goal - not necessarily 'grouping'. A good example of rewarding teamwork is the FFXI skillchain/magic burst system where players are rewarded with the opportunity to do additional damage based on the weapon skills they choose to use in tandem.
