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.
Nov 15 Loot sharing. Fools How stupid is the community about loot sharing? You know there is master loot right? Stop being dumb guys like holy crap. You also know that if you're the guy setting up a group or joining a group you have a option not to run or you can pick player's of different armor types... If you're a cloth wearer you just don't run or set up a group with other cloth wearers. Like this is something so simple and the community can't graps anything. I feel bad for blizzard sometimes with having to deal with brain power of this community. The community: "Oh, I didn't think about that. Derp, I'm an idiot."Plewtoe23 Nov 15
Nov 15 The most hardcore thing you can do. In vanilla? I have a few things that could be it. Playing on a perma death PvP server and kill kel'thuzad. Without dying even once. Being able to kill a mage/rogue/warlock/pally in all BiS gear Soloing a high end dungeon boss like rivendare or dark master gandling. Leveling to 60 with no gear or weapons or pet of any kind. That is by far the most hardcore, life threatening thing you can do in vanilla wowHavell7 Nov 15
Finally, as WoW Classic leveling can be long and arduous, we would like to recommend that you befriend people who are also leveling in your zone as you go by, as leveling in a pair (large groups are not advised due to problems with quest item drop rates and experience splitting) can not only make things faster and safer, but will also provide you with someone to chat with.
