WoW Classic is going to have updates rolled out in phases. There are currently six phases planned, which should be rolling out periodically.
Unfortunately, we don't currently know how long the gaps between phases
will be! We do know, however, what each phase is likely going to
contain. Blizzard appears to largely be modeling the releases based on
the roll-outs of the original World of Warcraft, but they are also
making a few modifications to make it run a bit more smoothly.
These are all of what is going to be in the game on release. Believe it or not, both Molten Core and Onyxia have already been defeated
within the first week of the release!
The signature dungeon of World of Warcraft is likely Molten Core. This is a 40-player raid that features a ton of fire wielding bosses and
culminates with the epic battle with Ragnaros the Firelord!Onyxia is
the main boss of the Onyxia's Lair raid dungeon. This is another
40-player raid where you face off against the large purple dragon
herself!
Maraudon was not originally released when World of Warcraft first launched. It was added in the 1.2.0 patch which was about a month later.
It's a 5-player dungeon that is recommended for players that are level
46-55.
This is pretty much how I remember PvP being during the launch of the original game. Players would fight it out sometimes, but more often
people would just wave at each other and try to get their levels in or
quests done. I imagine now-a-days, however, there's probably going to be
a lot more scuffling across the factions.
Dire Maul is similar to Maraudon in that it's a 5-player dungeon that can be run prior to hitting level 60. It can be found in Feralas,
and is recommended for levels 44-54. This was originally scheduled to be
apart of Phase 2, but is instead going to be released on October 15th
or 16th! The rest of Phase 2 remains the same
