Now is the best time to rejoin WoW.

Legion is coming out in 2 weeks, but if you buy it now you get a free boost to 100. If you buy it after launch you will NOT get the boost to 100.

Before you boost you can do class trial, which is temporarily play with a lvl 100 toon to see whether you like the class or not before you use your boost

There is invasions now which give a lot of xp and gear, also a lot of fun to participate in.

Demon Hunters have also been released, very mobile very fun class.

Nope, because you can only buy the box after release. Only pre-purchase gets you the boost.

Ah, good to hear that. Ok I stand corrected.
