To get Blacksmithing to level 300 is much effort. It is not that thing to make fast gold. There is always a lack of Blacksmiths though. Enchanters need rods of all kinds, melee classes look for Sharpening Stones and Weightstones with Counterweights, others buy Iron Spurs. Once you have learnt rare and epic recipes, people will always use your service to craft items.
So, if you happen to have two good 1h weapons, and are Fury specced, don't be afraid to try out dual wielding. Some people swear by it, and I can see why. Getting miss/parry with 2h weapon is cancer, and having two weapon swings for two different chances at crit, can really help smooth out your damage and make it less random. If you're still skeptical, I'd suggest trying it out once you get Thrash Blade, or if you happen to have a Flurry Axe. With really sick 1h weapons, dual-wielding can definitely feel great.

A different brand of challenge is presented by the PVP, which has undergone multiple phases and metas throughout the game's long lifespan. As in any competitive live game, some classes will be a fan favorite criticized as overpowered in one era only to be left behind in the next. The team says this is one of the main reasons it chose this specific iteration of WoW.
It is also worth noting that World of Warcraft Classic isn't exactly an archive from 2006. It has been rebuilt from patch 1.12, using modern data architecture and reaps the benefits of the modern engine. This means a lot of non-controversial quality-of-life features will still be present and it is possible to run WoW Classic servers on modern server architecture. As you can imagine, much has changed in the last 13 years in the tech space. That's before smartphones were even a thing. The modern engine no longer allows certain behaviours that could be used to get out of bounds, also adds widescreen monitor support and accessibility options! However, it does have the disadvantage of not being able to run on 32-bit systems which isn't that kind to older systems considering the game is from 2006.
HOWEVER, I did find out that there was an exploit to get around it (one of those rare exploits where you would WANT a bit of lag). Basically if you spammed “X” to sit/stand/sit/stand, then if a mob hit you while you were sitting and right as you were standing up, then it would register as a crit, but on the server side you would be standing, thus allowing the ability to proc.
