Wait, /sit to trigger crits is p-server thing? I distinctly remember people saying that if you sit, you will be crit when I played 1.12 Vanilla. On top of that - there’s that pally that one shot Kazzak in early Vanilla because he stacked a shitload of reckoning when it didn’t have a limit - it’s not inconceivable that he did it without /sit to trigger crits, but it would take him so, SO long to do that without /sit.
If you like playing solo – there’s no better option than the Hunter. Hunter is considered the most efficient solo-leveling class so you’ll ding level 60 in no time. As a Hunter, you will be able to tame various beasts across the world and use them as your pets. Pets help you tank groups of mobs and enable you to tackle some of the group quests alone. However, their PvE power falls off in the end-game, but their PvP potential is enormous. Skilled Hunters are a pain to deal with since it’s almost impossible to catch a masterful hunter.
Most people who have spent years playing massively multiplayer online games will tell you that there's something special about the first one you played, too—and WoW was the first for many people. You can become so swept up in the uniqueness of your first experience that you overlook many flaws. It's likely many look at WoW Classic with rose-colored glasses, just as many simply forgot which features were added when. And some of today's WoW players may be too young to have even played vanilla WoW as it once was.
