Also the iconic tank class, so if you pull aggro, you’re likely to survive if your tank can taunt off. Also, just add a threat drop then, there’s no reason every dps class shouldn’t have a way to reduce their threat. Why play a class that’s good solo, but terrible in group play? Mages are great solo AND in group play. Paladins as well. Every class that can heal or kite is great solo. There is no golden rule or commandment that a worst solo play class should be the best in group play. The reason warriors suck solo is because they need gear for hit, crit, armor, health pool, AP, and they have to tank/mitigate the damage and outdps the mob attacking them. Why level a hunter except be a gold farmer or bot if you want them to bad in group content. It’s stupid design philosophy and you’re assuming it all was intentional because of the last patch of classic.
Like I said, you are approaching this dogmatically because it was this way in classic it should always be this way. It was not even intentional brother. The strength of warrior is you’re tanky, a strong melee dps (every melee dps and dps in general should be “strong” or comparable whether through having more dps or burst) and rely on the rage resource to dish out more damage, so the more you get hit or crit/hit mobs the more abilities you can use to increase your damage, but you have no healing and can’t cc, kite or are as mobile as squishier classes. Realistically, a more squishy class like mage, warlock or shadow priest should out dps/burst a tanky class. A problem with dots is they don’t scale at all in classic and are best for longer fights, which do not exist in classic as well. Not to mention every other class has mana as a resource and often had less thought put into it than other classes. Hunters were supposed to have some version of focus at first.
