Some quests in my guide are marked as "SKIP" and colored in red. These quests are simply either too hard to solo or not worth the XP/time and are skipped. My guide will only list SKIPPED quests if the quest is a direct follow up after completing a quest, not one that you have to click the NPC again to get it. If you hover over the skipped quests, it will give info on why it is skipped in the guide (unless that info is already listed directly in the guide text).
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.
Fortunately, WoW’s modern editor is able to perform some of these data conversions, and for the terrain data we could convert it with the same editor we used on Battle for Azeroth. The modern editor “knows” how to load the old terrain format and how to transform it into the new terrain format and export it to the modern engine. This corrected the issues of campfire placements and the appearance of trees, among other things.
