World of Warcraft Classic is currently in beta, which means some players are getting a chance to experience a much older version of the MMO ahead of its release. WoW Classic is based on how WoW played in August 2006, back around update 1.12. Back then, things were different. Tauren hitboxes were much larger, sitting could cause certain combat effects to not trigger and completed quests were marked with dots and not question marks. Strange days.
As of right now, there is no official exact release date, aside from confirmation of summer 2019. It is expected to hit the internet roughly mid-July, or possibly in August. Something as highly anticipated as WoW Classic could launch with weeks of notice and still break records. As of April 21st 2019, World of Warcraft Classic has entered internal employee alpha testing.
An extremely rare herb, one is needed for each flask that an alchemist crafts. Only one black lotus is up at a time, and it can be found in Silithus (one north of AQ gates, one in crystal vale) and Winterspring (one at Mazthoril blue dragon area, and one south of the main road in the western Furblog area). Apparently also one in Eastern Plaguelands, I never saw it.
In terms of what the World of Warcraft Classic Best Classes are, Warrior and Priest stand out almost instantly. This is partly due to the fact that Protection Warrior is the only viable Tank Class in WoW Vanilla Patch 1.12. Both the Proc Warrior and Priest are required for Raids and when combined in a PVP setting can be a fierce combo on the battlegrounds.
That's not to say that everyone has an unrealistic vision of what vanilla WoW was like. There were already plenty of people on the WoW Classic forums pointing out that perceived bugs are just recreations of the original game. And as noted before, a flaw to one player is a key component of the original positive experience to another. WoW Classic will surely please plenty of purists in spades. But this goes to show that it won't be for everyone who has fond memories of the game circa 2006.
