Enjoy some string cheese while you play!
I hope for you that they don't pull a Maplestory and make a server like Reboot to relive "the old maple experience"....
Classic Vanilla World of Warcraft? You have a guestimate when? I would learn from the Private-Server, and then play the Official-one and pay the monthly-fee. But right now, it's too early, we don't know when.
From your posts of materials, I would guess you are into Traditional-MMOs like myself? The new-WOW with Legion is terrible! The Combat of that is Rotational because they introduced the Cooldown, but the old-WOW, there is animation with no Skill-Cooldown, so you can spam the Skill(it is all stat-based). Yes, the old-WOW is that Traditional and grindy, which is a positive-thing for me.
If they would bring back the Classic, I will play it with no questions. But the current-new-WOW, it became garbage.
